Some areas are going all digital and are using DTA's. Just a basic box that has no composite input which would have added very little and had better PQ. This DTA does have IR support for older Series 2 models. Now your IR enabled Series 2 can still record those digital channels. DT models can only record a 2nd limited basic channel since limited basic is the only analog tier under this new measure. Just a basic little box that might just work on the older Tivo models.

So this DTA is just a stripped down cable box?

It seems to me it is a QAM tuner that can map to channel numbers, and possibly has an EPG. It apparently cannot decrypt encrypted channels, or use any 2-way services.

I am going to add, it cannot be used directly with a Series 2 DT, since it has no A/V out.

The DTA doesn't have an EPG.

EPG == Extended Programming Guide ??

I guess this box would allow my TVs that are connected straight to the coax to go beyond channel 99, yeah?

That would be worth it to me, but kind of sucks if it doesn't have a guide.

Anyone know if this is available in NH?

The DTA can only get Digital starter but it does go over ch. 100. Philly, SF, and Seattle are next in the DTA rollout. Portland is the first market for it. It also uses the same channel numbers as the boxes.,

Here in New England, I've seen some other kind of little STB that kind of looks like this DTA thing....

Both my neighbour and my tenants have it... it seems to be what you get if you want digital cable, but don't want HD or DVR service. So instead of getting the bulky Moto box, they give you this little thing.

I've seen the EPG on it and it uses pretty much the same remote as the moto...

Any idea what that thing is called?

For manual use though.

For full control, the STB needs to connect to the A/V input on the Series 2 DT DVR.

And yes, EPG means Electronic Program Guide.

Re-running S2DT's Guided Setup as a test proved you're right, unfortunately.

There is a workaround, but it's probably not cost effective for most applications:

Why would they want to deploy an all digital box that's not capable of 2-way services? (ppv, on demand,...) Aren't they cutting themselves out of possible revenue streams? This thing can't even tune switched digital channels, right? (not 2-way)

The DCT700 is pretty damn cheap to produce in itself. Is this new box that much cheaper to produce? Pace has a reputation for ultra low end stb's, but are they THAT cheap?

Numbers that I've seen are that the DCT700 costs $50 - $60 and the Pace box is less than $50. Ten dollar savings on 12 million boxes equals $120 million.

You'll need to use an IR blaster and the DT will become a ST.

On the 6:30p news last night KING announced that Comcast channels above 29 (Limited Basic) will go digital in April. As the Times article states, Comcast will supply two DTA's for free and additional DTA's on the same account will cost $1.99 mo. each.

If a demodulator is used to convert DTA's Ch.3 to composite an S2DT could continue to record two programs at the same time.

QZ1
12-09-2008, 08:26 PM
The DTAs are SD clear-QAM tuners using an RF connection. They are similar to the integrated clear-QAM HD/SD tuners in TVs (w/o the HD), in that they only provide clear Digital channels with station IDs; no interactive features. Therefore, those that have clear-QAM TVs won't need these boxes for SD Expd.

They will be using the filtering system for blocking non-Expd. customers from getting Expd. It has been speculated that they will using the same frequencies, so as not to have to re-install filters. There will be extra bandwith in those frequencies, but, so far there have been no reports of HD Expd. channels being in the clear.

So, having a clear-QAM TV only helps if your TV size to viewing distance ratio is such that PQ is unimportant, and SD will suffice. HD will need a box or CC. I am waiting for tru2way to become common.

I have heard that DCT700 were $70, and the DTAs were $35. However, other quotes may be more accurate. Based on what I had read, I had speculated that the rental fee instead of ~$4, would be ~$2, and that is what it turned out to be.

I am guessing that the DCT700 must use its security in order to function, while the DTAs don't have to use it. Also, the DTA uses a lesser security protocal, but it still would require an FCC waiver to be able to use.

I don't Tivo so my question may be moot, except this is one of the only places I've seen any discussion on the Comcast DTA's. I have the expanded basic service with Comcast. Apparently we can get two DTA's free and then they'll charge a rental fee for anything after that. We have more than two tv's in our home and I don't like the idea of extra rental fees. Does anyone know if buying the likes of the Motorola DCT700 will work for our extra tv's that we won't have Comcast DTA's for?

Thanks.

Comcast is currently providing digital simulcasts of Extended Basic channels (analog channels above Ch. 29) unencrypted. If their pitch on digital conversion is to be believed they'll continue to do so:

http://seattletimes.nwsource.com/html/brierdudley/2008480563_brier08.html
"What we're trying to do here really amounts to a free upgrade," Comcast's regional spokesman, Steve Kipp, said.

HDTiVo cannot map these digital standard-def channels manually so must be used with a CableCARD. If HDTiVo is a Comcast sub's only digital outlet, fine; even an S3 user would have to pay only $1.79 extra for a second CC. However, when a Comcast sub employs a standard-def digital STB in addition to HDTiVo, Comcast's $5.20 'Additional Outlet Fee' applies.

Therefore the cheapest alternative, when a TiVo customer already has one, is to use a Lifetimed S2 and Comcast's free DTA along with HDTiVo. Using an S2DT with a demodulator (like an old VCR) will enable recording two programs at the same time and allow S2DT's tuner to access analog channels 2 through 28 directly.

If a user doesn't have a Lifetimed S2, an option which costs more but offers Comcast's Limited Basic OTA channels in hi-def as well as digital Extended Basic channels with no 'Additional Outlet Fee' is to get Sony's HDR-HDD250 DVR, available from eBay and other sources for around $400. Sony's discontinued but impressive DVR has 250GB of storage and the ability to manually map unencrypted digital channels without a CC (although it can use a CC as well.)

Comcast plans to completely phase out expanded basic service eventually, doing away with the midrange tier between bare-bones basic and the full digital package. It's already made the prices of expanded basic and "start digital service" the same $55.75 per month.

That FAQ about expanded basic channels being encrypted directly contradicts what the Comcast Chief Ops Officer said for the Portland migration (http://www.multichannel.com/article/CA6611062.html?q=comcast+dta). They're providing the channels in the clear, at least initially. If they're planning on implementing security in the DTAs, they will need a waiver from the FCC that they do not currently have, because these are new devices which would fall under the FCC's separable security mandate (i.e., Cablecard). I smell a court fight if they don't leave it off.

I can see where the FCC might grant them a waiver, so long as all the rest of their leased STBs--the ones capable of tuning premium channels, etc--used M-Cards. There's a compelling reason for internalizing security protocols in these things (the need for them to be extremely inexpensive). Of course, if they start deploying them before securing a waiver, they might get slapped with a fine.

I don't think that they can protect these channels with addressable band pass filters the way that they protect the analog ones, but if they can, that would definitely be the way to go. It would still suck for TiVo users opposed to leasing CableCARDs :).

Right now the digital equivalents of analog Chs. 30 through 78 are in the clear and analog Chs. 30 through 78 are still available.

Was Comcast spokesman Steve Kipp mistaken in the Dec. 8 FAQ?

Q: What about TVs with QAM tuners - can they get signals directly from the cable? (NEW)

A: No. "They would need a digital adapter, a standard set top box (DCT) or a CableCard in order to view the channels," Kipp said. "The first CableCard is free with each additional CableCard costing $1.79 per month." This is because the signals will be scrambled/encrypted, and a device from Comcast is needed to descramble them.

Some Comcast experts on AVS Forum say, that the filtering system can, and will, be used for now. Comcast has wanted to abandon this system for a while now, due to lack of security and high maintenance costs, but can't just yet. When, and if, they can use any form of encryption for SD Expd. Basic, they will.

It sure seems like it, as Comcast has no choice at the moment, but to send them as clear-QAM, but we don't know for sure, I guess. If so, the next question would be, was he mistaken unknowingly or on purpose?

Just picked up two DTA's from the local Comcast store. I'll connect one to a S2DT's line input via a VCR and report on pix quality vs. S3 tuned to the identical standard-def digital channel.

I was surprised that Comcast has DTA's already. They're from Pace.

The Comcast rep. told me that the actual switch to digital only Extended Basic (Chs. 29 through 78) won't take place until late Spring 2009. Now Chs. 2 through 78 are available both as digital and analog. Digital versions are currently clear QAM unscrambled.

Sony's DHG-HDDXXX DVR's can manually map clear QAM and provide TVGOS EPG data. Hopefully TiVo's S2 will provide the same functionality via the DTA route.

Now that the new Moxi hi-def DVR maps clear QAM perhaps TiVo might reconsider providing the same functionality to HDTiVo.

BTW, does anyone have a clue regarding S2's supported IR codes for tuning a DTA through the TiVo interface? Wonder if a DTA utilizes the same code as Comcast's Moto STB?

If TiVo has a Comcast DTA converter code it's not at
http://www.tivo.com/setupandsupport/supporthome/index.html

Comcast's Moto STB uses a different code.

So at present I can't control Comcast's DTA with TiVo's IR emitters. Hopefully that will soon change because the little DTA is very useful. :up::up::up:

Supplying S2DT's line inputs from the DTA through a VCR used as a demodulator results in an excellent image on my 42" hi-def LCD flatscreen. Of course using both S2DT's tuner and line inputs allows recording two programs at the same time.

S3's analog tuners are somewhat better than S2DT's tuners. At first I thought S2DT had relatively poor tuners but quickly realized that the signal was split between the S2DT and the DTA so the S2DT's signal was 3.5 Db down from the S3's. I swapped coax's thus supplying the S3 with the lower signal. Now the S2DT provides slightly better images than those from S3's analog tuners. S3, from its digital tuners, offers the best standard-def images available.

So, for standard-def, S3's digital is best. S3 can provide an analog image slightly better than that from a demodulated DTA but only when supplied from an unsplit source. S2DT when supplied from an unsplit source provides an image slightly poorer than that from a demodulated DTA, but when its source was 3.5 Db's down the S2DT images were relatively poor. All comparisons were sourced from the same Comcast channels in both their digital and analog versions.

Aside from pix quality the DTA presently offers several digital channels unavailable from Comcast's Extended Basic plus a line-up of music and FM channels. DTA of course doesn't provide Comcast's hi-def OTA simulcasts, just digital standard-def versions. It includes a Universal Remote which can be programmed to operate most TV's including LCD and Plasma flat panels and select between volume and mute controlled from either the TV or DTA itself (but not from a home theater audio system). It's even got an IR receiver extender cable if a user wants to hide the li'l box.

Hi everyone. I just picked up my three DTA boxes from Comcast (Pace DC50X). I have a Toshiba RS-TX20 (single tuner, DVD reader/writer) that I'm trying to connect one of the DTA's to, but I'm having some problems. Here's what I've done so far:

Connected the DTA between my incoming cable signal and the RF IN on the TiVo
Mounted the IR emitters on the DTA
Connected the IR cable to the TiVo
Rerun the Guided Setup, and selected COMCAST DIGITAL ADAPTER as the brand of cable box

The problem is that it fails the channel changing tests (the channel doesn't change for any of the tests). I went back and selected PACE as the cable box, but still had the same problems. I know the DTA is good, since I set it up on another TV and called to have it authorized.

Does it sound like a problem with the placement of the IR emitters? Has anyone successfully set up this DTA with their TiVo yet?

Thanks for any and all help.

Thanks for the input. I just read that (posted by "duckfan") on the TiVo forums. Does TiVo provide a way to manually enter that IR code?

Also, I notice that there is an "IR input" jack on the back of the DTA. Can I connect directly between the TiVo and the DTA and avoid the IR blasters completely?

Well, currently their business model is such that you have to subscribe to more expensive 'digital cable' to gain access to on demand.

I'm guessing they want to continue to have the ability to charge more.

But why they can't just develop a cablecard box that they can give and take channels based on your package doesn't make sense to me.

Yes, it would cost more, but they could take advantage of the 'impulse buy', people who upgrade service over the phone...

Yes, it would cost more, but they could take advantage of the 'impulse buy', people who upgrade service over the phone...The entire purpose of DTAs are to be as inexpensive as possible because the providers expect to have to distribute millions of them in order to convert to all-digital systems, most of them at no charge to the subscriber (systems that have rolled them out have offered the first two for free). Making them even $10/unit more expensive wouldn't be likely to be made up by people upgrading to higher end service over the phone.

Why not...? Dish Network and DirecTV don't seem to have an issue with it...

The money made on PPV will help off-set it... The random person that might order a boxing match on PPV will help...

And people upgrading to the 'sports pack' because a big game is on NFL network... or people adding HBO because a new series is starting...

Small dish satellite is all-digital and always has been. Basic Cable is all-analog and will be until cable companies pull the plug on much of it. The change isn't mandated and is taking place to benefit cable companies, not their subscribers.

Many (most?) extended basic customers don't want cable boxes. Just another gadget to deal with (and in many cases pay extra for!) Comcast is making the change as palatable as it can with the simple and (mostly) free DTA.

I recently picked up and installed a cable box for an elderly neighbor. She didn't want one but was afraid of losing much of her Extended Basic service. I installed a DCT700 and showed her the EPG but she may never use any features beyond what the DTA would offer. Comcast offered either the DCT700 or the Pace DC50X for free because she didn't already have a box. Comcast's standard DCT700 remote (which also controls DVRs and accesses VOD) is much more intimidating than the Pace DTA remote.

It's time for TiVo to come up with a working S2 code for the Pace (and/or Moto) DTA, or if they can't, at least to post here why they can't. Otherwise a suspicion being planted is 'planned obsolescence', which with regards to TiVo service doesn't add up!

There's no TiVo IR code currently available which enables channel changing on a DTA.

A DTA can be connected to an S2 and will provide a decent picture but DTA tuned channels must be changed using its OEM remote. Using a DTA with an S2DT will retain S2DT's capability to record two programs at the same time (with a little extra hassle) without paying anything extra to the cable company.

Glad to see that TiVo now acknowledges that DTA's aren't supported.

I'm actually interested in the idea of a DTA, I have no use for a "full featured" digital box. Since I use my TiVo box as a receiver, I NEVER turn on my digital box (part of a "package")... all of the channels I care about are in the "analog" area right now

But now it sounds like I should NOT get her the free DTA because she won't be able to use the Tivo Remote -- is that correct? She won't be able to handle having 2 remotes, it needs to be as simple as possible for her to be able to use it.

If your grandma is using Analog cable you don't need a DTA. This only is required if your grandma used rabbit ears."DTA" stands for "Digital Transport Adapter" which are very low cost, rudimentary digital cable STBs. Cable systems are using them to convert to all-digital service, freeing up tons of bandwidth because they can fit 10 standard-definition digital channels into the space consumed by one analog channel. Unfortunately they have millions of lifeline- and extended-basic subscribers who have legacy analog televisions connected without cable boxes (and without cable box lease fees). They have to provide those subscribers with boxes they can use to tune the same services at little to no cost.

S2 TiVos in an all digital system will have to use some kind of cable STB. TiVo is saying that they don't currently support DTAs, but I think that they need to provide support for them, ASAP (of course, it's only S2 users who are screwed by this and they might not care). S2DT users are screwed forever, unless there's some way for them to use two cable boxes.

After the cutover you won't be able to record two Extended Basic channels simultaneously on S2DT with either a DTA or STB.

But, if in Guided Setup you program S2DT for both a digital STB and analog Extended Basic, after the cutover if two programs conflict, one of them Extended Basic, the other Limited Basic, and you use a DTA and pretune it with its remote and tell S2DT to get 'em both, it will. There is currently no TiVo IR code for a DTA!

If a Comcast account has two or more Extended Basic outlets, both with S2DTs, the choice is between paying $5.20 mo. (in my area) to Comcast for additional digital STBs for the convenience of using TiVo as designed or using one or two DTAs (tuned manually) for free. (The options are considerably simpler than writing about them coherently. I hope I've at least partially succeeded.)

TiVo, for its own convenience, has omitted two capabilities, the lack of which causes TiVo users to incur Comcast's Additional Outlet Fees: S2's can't control DTAs and HD/S3's can't manually map unscrambled QAM channels.

I proposed using a VCR as a demodulator earlier in this thread and succeeded in restoring S2DT dual tuner functionality by doing so.

Comcast is not going 'all-digital' in my area. Limited Basic Service, Ch.'s 2 through 28, will remain analog.

All Basic Service channels are currently simulcast in both formats. After Comcast digitizes Extended Basic, only Chs. 2 through 28 will be available as analog from a wall outlet without a STB or DTA.

Therefore split the coax outlet between an S2DT and Comcast's DTA. Send the DTA's Ch.3 coax output to a VCR and then from the VCR by composite cable to the S2DT's line input. The S2DT will receive separate analog signals from Limited Basic's Chs. 2 through 28 on its line and coax inputs and Extended Basic's Chs. above 28 on the line inputs. Chs. 2 through 28 will still be tuned by S2DT's internal tuner while all Basic channels are available from the line input. The S2DT retains dual tuner functionality.

The primary reason not to go with a DTA on S2DT as things now stand is that the number of channels conveniently received through S2's analog tuner(s) is about ⅓ the number a STB would access. If a DTA was only required when two programs conflicted it would be a workaround worth considering.

You should probably clarify that statement. I AM able to use IR code 10104-B to control my Comcast DTA (Pace DC50X). See post #52 in this thread.

Found the answer to this one posted here (http://www.tivo.com/setupandsupport/technicalsupport/issueswithmydvr/Advanced_Troubleshooting_for_Channel_Changing_with_IR_Contro l.html). 10104-B is indeed the correct code. The channel changing is now slower with the DTA in the loop, but at least it works.


Thanks for your reply. I haven't gotten back to this thread until now. It wasn't clear from post #52 that IR code 10104-B had actually worked for you.

I thought that Advanced Code 10104-B might only work with single-tuner S2's when it didn't work with a S2DT with 9.3.2a s/w (post #57), but have since tried it on both single and dual tuner S2's without success. Wonder what's different about Toshiba RS-TX20's s/w?

Has anyone else had any success? It's not convenient for me to swap the single-tuner S2 back in for testing right now.

9.3.2a-01-2-565

So there is a small difference between our versions. Not sure what changed between 9.3.2 and 9.3.2a, and if that would result in the IR code working for me but not for you.

The "a" version went to broadband network users to fix Amazon download issues. Phone-connected users never got it.

Not to stray too far off topic but I purchased 2 Digital Stream D/A converters and one of them had a cable option but the other did not. I tried the one that did the 1st day I got limited cable and it didn't work.

Is it possible that it didn't work because I don't have digital cable with Brighthouse? Or is it just something they put in the box's menu that will never actually work??

I did find it curious why a D/A converter would ever have an antenna/ cable option if it was never going to work with cable. :D

Strange that it's working on my RS-TX20 and not yours :confused: I'll check the S/W version that I have, but I think it's the same as yours (9.3.2-01-2-565). I'll check and post back.

The article from the TiVo forum about entering the advanced setup mentions that if you've passed the "Channel Changing" step, you may need to unplug your TiVo so that it repeats the "Guided Setup". I agree that you should be able to go to it directly (as you did), but maybe it's worth running the Guided Setup from the start per the instructions:

LINK (http://www.tivo.com/setupandsupport/technicalsupport/issueswithmydvr/Advanced_Troubleshooting_for_Channel_Changing_with_IR_Contro l.html)

SUCCESS!!

As per your suggestion I reran Guided Setup instad of working from the Channel Changing page.

I used Pace's remote extender instead of the IR receiver in the DTA along with the original TiVo supplied IR blaster.

I selected Comcast Digital Adapter as the STB.

The diagram for Series 1 or Series 2 without a digital cable box (basic cable) on the link below hasn't changed and still doesn't depict an IR blaster.
http://www.tivo.com/setupandsupport/technicalsupport/compatibilityhelp/All_digital_cable_and_the_Series1_or_Series2_Single_Tuner_DV R.html

After Guided Setup ended I removed Pace's remote extender and attempted to change channels using TiVo's IR blasters directly over the DTA's IR receiver next to the green LED, but channel changing NO LONGER WORKED!!

So the secret is employing Pace's remote extender to enable DTA channel changing!

The remote extender employs a stereo-style three conductor mini phone plug while TiVo (and other) IR blasters employ a two conductor mini phone plug so I'm not even going to attempt a direct wire connection between the two jacks!

Unfortunately I can't conveniently check right now whether TiVo (brand) single tuner S2's work the same as Toshiba (but see no reason why not) as I'm testing whether an unsubbed 240 S2 will continue to record manually after swapping it in place last month. If that S2 still records manually two weeks from now I'll swap it out and see if an S2DT can control a DTA using the IR extender.

Hey, cool! Glad to hear you got it working.

So, just to understand, you found you had to use BOTH the TiVo-supplied IR blaster (blaster end wrapped around the IR port of the DTA, other end connected to the TiVo) AND the Pace-supplied IR Extender (connected to the Pace DTA) in order to get channel changing to work with the TiVo remote. Is that correct? What IR code was used?

Mine's still working with only the TiVo-supplied IR blaster, and IR code 10104-B. As I mentioned earlier, the channel changing can be a little slow, so I might try the setup that you are using to see whether it's faster.

EDIT: Reading your post again, it sounds like you have the TiVo IR blaster wrapped around the IR port of the Pace extender, and not around the IR port of the DTA. Is that correct?

02-04-2009, 08:09 AM
For me TiVo's Comcast Digital Adapter code, which most likely is 10104-B, works perfectly when TiVo's IR blasters are placed over Pace's IR extender but not at all when the TiVo blasters are directly over the IR receiver next to the green LED on the DTA. The DTA's remote control works perfectly when pointed at either IR sensor. The IR sensor in the DTA appears quite sensitive; the DTA remote doesn't even have to be pointed toward it.

It turns out that when TiVo's IR blasters are placed directly over the DTA's IR receiver they grossly overload it. Even placing them six inches away doesn't work. But when placed three feet away or ten feet across the room they work fine!!!! Practically speaking, using a DTA's included IR extender is a better solution, but the mystery of controling Pace's DTA through its IR receiver has been solved.

I also could not get the Tivo IR to work directly with the DTA, had to use the extender they provide. After I taped them together to block out other signals, they worked nicely.

I needed to set to 1 digit, Enter required, before I got 10104-B to work properly.

Note that even if you're paying for more channels, you will only get Digital Starter channels with the DTA, although this is more than the analog I was getting before. I assume this is because the others are encrypted, and they're not allowed to use encryption on this device yet.

The only thing stopping me from trying is that I'm not sure that I wouldn't accidentally put too much juice into the DTA box. I've taken apart the external remote sensor for the Pace box, and it is a fairly simple setup, I just don't want to give the DTA more voltage or current than it is specced to take.

At an early point during my trial and error approach before becoming aware of the specific differences I actually ran a cable with stereo mini-plugs at both ends directly between TiVo's two conducter output jack and the Pace DTA's apparently three conductor IR extender input.

Didn't work of course, but didn't cause damage to either S2 or the DTA.

How did you wire the three wire plug to the two wire plug? Wouldn't there have been a spare wire on the DTA's end? Or did you use a three contact plug (the type found in stereos) for both the Tivo and the DTA? That would have left the ring circuit in the DTA open. In any case, I think I'm going to check it out, albeit carefully. I think the external IR receiver on the DTA is powered, and I can't imagine that it would be good to deliver that to the Tivo.

I tried the 10104-B code with an IR emitter married to the extender, no luck. Next I placed the IR emitter in front of the DTA and channel chaging worked O.K. I found that it worked more reliably with the extender unplugged. Next I tried the TIVO recommended code for the Comcast DTA (10104-C) and channel changing seemed to work faster.

I'm using one of the cheap visible light IR emitters being sold on ebay cause I lost the TIVO blasters years ago (used serial cable on old cable box).

Just to throw another possible solution for folks out there. I tried for about two hours tonight to use the Tivo IR Blasters with the Comcast DTA extender with mixed luck. Sometimes the channel would change, sometimes not, sometimes it would, but go to the completely wrong channel.

I did try the IR Blasters in several places on the DTA and what really worked for me was to adhere the one blaster on each side of of the DTA pointing in toward the IR receiver. The DTA looks a little like a crab now, but it seems to be working.

I did some further testing and found the blasters worked best when they extend beyond the front of the DTA by as much as possible. I left about 1/2" of each blaster "arm" stuck to the device.

I also tested 10104 A, B, & C with a stop watch and found no major difference between the two, each one would have changes as short as 4.8 seconds and as long as 6.5 seconds, but none seem to average shorter overall.

Thanks for the post, tomeh. I've got mine mounted in the usual place (top/bottom of DTA, centered over IR sensor, sticking out about an inch), and it seems to work OK. The only strangeness I've seen is that when I use the TiVo remote first thing in the morning, I get strange channel-changing results for about 3-4 minutes, then it works correctly. For example, if I'm on channel 5 and want to go to channel 2, if I hit CHANNEL DOWN, it sometimes doesn't register. Other times if I try to CHANNEL DOWN to a 3-digit channel (617), it will only enter the first digit and take me to channel 6. After a few minutes of this, it seems to settle down and I can cycle up and down through the channels with no problems.

Since I'm using the DTA, it doesn't receive the complete lineup, so I've gone in and removed all of the channels that the DTA doesn't get. I originally forgot to do that, so the CHANNEL UP/DOWN would try to go to channels that I didn't get and that would cause strange results with the DTA.

S2DT can receive a DTA's output on ch. 3, but can't control a DTA except when the DTA's output is received through S2DT's composite/S-video line input. Using an old VCR as a demodulator provides both DTA control and dual tuner functionality for S2DT.

What settings are you using for the number of digits that must be entered to change channels and whether or not pushing an enter command is required?

I use one digit and no 'enter' with fair success, but on occasion, usually overnight, TiVo loses the DTA's output. Scrolling one channel up or down brings it back. I'm still troubleshooting the problem. It may be caused when a Teleworld Paid Program is recorded and TiVo attempts to return to the previous channel it was tuned to.

I use S2DT's IR emitter adjacent to the DTA's IR extender but have found that if TiVo's emitter is several feet in front of and pointed to the IR receiver on the DTA itself that also works well. If my S2DT's emitter is adjacent to the IR receiver on the DTA it doesn't work at all.

That has been my understanding also (in fact I posted as such several pages ago), but I have been told by TiVo management that a software change was made to allow the S2-DT to accept Line-Input on coax and therefore will work with the DTA. Again, I'm not looking for dual-tuner status, just a simple coax input of digital tuned channels.

The short answer is: YES, but...

It wasn't easy and definitely not spelled out in Guided Setup steps.

I selected the following options:

1. Cable with a cable box.
2. NOT splitting the cable as per the diagram and thus losing dual tuner capabilities.
3. Comcast Digital Adapter
4. 1 digit channel entry
5. 'Enter' command not required
6. No premium channels

At first the screen stayed black when attempting to change channels so I went back to the screen verifying that a given station is on a given channel. The first two times that screen stayed black before and after selecting the correct choice.

The third time was the charm, it showed a picture! The first test or two that followed proceded uneventfully. Then the black screens returned. After backtracking a test succeeded. Then (figuratively) two steps forward, one step back. After backtracking several times all the tests eventually succeeded.

Cable line-up was shown as 'Comcast- Digital' so I had to go to the Channel List to delete all the channels that the DTA doesn't receive. Standard-def OTA channels and subchannels are offered but no hi-def. Only two channels that the DTA receives aren't shown on the Channel List, one (thank God!) a religious channel while the other a Comcast Channel similiar to Dishnetwork's Charlie Channel.

The DCT 700 needs no IR port, since it "Receives" the IR signal with its IR sensor, form TiVos IR blasters, which connect to TiVo's IR port.

5. Right now Extended Basic Ch.s 2-78 are still analog with a digital simulcast. After the transition all channels above 28 will be digital only.
6. 3-digit is fastest and most reliable. DTA accepts single digit entries but then pauses slightly to ensure that more digits aren't coming. If leading zeroes are sent DTA tunes instantly to single digit channels. Comcast provides a handful of 3-digit bonus channels with a DTA.

This thread confused me a bit ;) I've got a Toshiba RS-TX60 (single tuner series 2) - I should be okay with the DTA, correct? We're getting forced to change next month (SF bay area), so we need the DTA for the Toshiba, and then cablecards for our TiVoHD, I think. The friendly folks at Comcast were confused by my situation (and couldn't even tell me if they'd be sending M-cards or S-cards, but that's another story...) - but hopefully I'm good to go for the DTA?

I'm not in Oregon. I'm in Washington.

And, as you note, it didn't work the way the steps described; with the DTA hooked up to RF Coax In under the version of the TiVo software that was installed at the time I was doing this nearly two weeks ago, there was no option to select any type of cable box.

So it clearly doesn't work all the time, though fallingwater indicates it was a hassle to get this to work. Not a good thing for regular, normal TiVo customers who have other things to do with their time than spend a half-day troubleshooting getting a Series 2 Dual Tuner TiVo to work with a DTA.

Incidentally, TiVo did send out a Service Notice email to customers in Washington State this week (the week of the Comcast digital changeover in my area) telling Series 2 Dual Tuner owners to go to the TiVo support page called "All-digital cable and the Series2 Dual Tuner DVR." (I'd post the link, but the Forum software won't let me.) Tellingly, this page still does not say a DTA will work with the S2DT, and instead stresses that a regular cable box is important.

6. 3-digit is fastest and most reliable. DTA accepts single digit entries but then pauses slightly to ensure that more digits aren't coming. If leading zeroes are sent DTA tunes instantly to single digit channels. Comcast provides a handful of 3-digit bonus channels with a DTA.


My question is in regards to your answer in #6. I installed the DTA to my bedroom LCD TV. I'm wondering if my ATSC tuner will be able to tune in all the new digital channels without having to use this DTA box? The main reason I don't like it is because it's not giving me the HD locals that I normally would get with my QAM tuner.

And the handful of 3-digit bonus channels seem like mostly duplicates of other channels. I'd prefer to get all my channels I normally get in my Digital starter package on my TivoHD, but I guess that isn't the case without a Digital Set-Top Box. I might have to just fork out for another digital set-top box at this point.

Your LCD TV requires a QAM tuner, which is standard, to receive all unscrambled cable hi-def channels.

What Series is your TiVo?

S2 requires a DTA to receive standard-def QAM channels or a digital cable STB to receive premium channels when subbed in standard-def format. A hi-def cable STB is required for S2 to receive hi-def channels in standard def format.

HDTiVo used without an 'M' CableCARD will receive all unscrambled QAM channels without EPG data and will map those channels with EPG data when an 'M' card is used.

I have an original Tivo, an SVR-2000, and am trying to sort out what to do with my hook up. Essentially, we in the SF Bay Area are going to lose all the higher channels after April 6. I have four DTAs in place but the one with the Tivo is a problem and I am loathe to give it up, as I paid a one-time lifetime subscription about ten years ago. The DTA has an IR signal receiver input jack and I am wondering if I could hook the IR out jack from the Tivo into the DTA IR input, to control things. The DTA expects to see channel 3 downstream so that may be a problem.

You repeat guided setup. first off.

Second, since you have a series 1, it has an IR blaster LED in the front. You can place the remote IR sensor from the DT box next to the TiVos front IR blaster.

I could not get the Tivo IR Blaster to work with the small Pace DTA that Comcast gave me.

After reading this thread, I placed the DTA IR Extender over the sensor on the DTA box...now the IR Blaster works using the default code that Tivo chooses when you set up your cable box as Comcast Digital Adapter.

Thank you.

Ok I'm worrying proactively but just to make sure I understand....

I have a S2 Dual Tuner used with Comcast in Toms River NJ. We have not received any notification of change to all digital. I just purchased the Tivo the other day as a closeout from Radio Shack.

Right now I have a Sci Atlanta box on input 1 and coax going into input 2 and I'm able to record two channels at once.

When my area switches to all digital I'll be able to still use both tuners?

Comcast is switching to mostly digital at the end of April for me. I was hoping someone could verify if the following setup could work for a S2DT.

I currently have a digital cable box and analog hooked up to the tivo.
Can I split the cable input so one end goes to the digital cable box and then the tivo, the other end goes DTA -> VCR -> Tivo?

I haven't seen any mention of using two DTA's or one STB and a DTA.

Also, if the above setup works, is the VCR then just working as an oversized adapter, such that I don't have to leave it on or anything? Also, do I then program the remote to control the DTA or the VCR?

If your service switches to 'all digital', not without changing your setup as outlined in the link below. But if your service switches to 'most digital' then, yes!

Connect the digital cable box's composite output to S2DT's composite input. Connect the DTA's output to S2DT's coax input. You don't need a VCR. Follow the steps in the post below:

I'm confused by the wording of the other post you linked me to.

I'm going to keep the digital STB connected to the tivo with composite cables. Currently, the tivo controls the STB through IR. (My STB doesn't have a serial port.)

Once I attach the DTA through coaxial, how do I control the DTA and how should I adjust the channel lineup?

classicsat
03-30-2009, 09:22 AM
You don't. Or you remove the cable box. The DTA box will be controlled with an IR blaster.

To clarify what fallingwater said; If you leave your setup alone, you will get dual tuner for the remaining analog channels.
To add:
You cannot get full dual tuners by adding a DTA box. The Series 2 DT will only work with one box of any sort at all. You need to choose between cable box and DTA box.

If it were me, I'd leave that setup alone, and use the DTA convertor elsewhere, or to supply the TV tuner directly, using the DTA remote to control it.

No; but it's somewhat of a hassle:

Connect the coax from the wall to the DTA and the DTA's output to S2DT's coax in. S2DT's channel list in TiVo Central Settings has separate entries for 'box' (digital) and 'cbl' (analog) versions of the same channel. Delete all 'cbl' channels except for the channel (3 or 4) that you set the DTA's output to with the switch on the back.

Control the DTA with its own remote; S2DT can't tune a DTA when set to tune another STB.

All recordings from the 'cbl' channel must be tuned from the DTA's remote and set up as manual recordings on S2DT. The only time you'd use this setup to record manually would be when there was a conflict with a previously scheduled 'box' recording.

Have S2 (not a dual tuner) and was fussing with getting the Comcast DTA (Bay Area) to consistently change to the right channels. Took your advice and just plugged in the Comcast DTA Extender, placed it next to the Tivo IR blasters (which are still mounted on the Comcast DTA as Tivo suggests) and it all worked as advertised. Kinda strange, but it works.

It is not a hardware issue, just software. However TiVo's philosophy of the device would likely mean there will be no dual-digital support.
Gett ing a TiVo HD is the only sure solution to the problem.

Question for this thread.

I've got the S2 (no dual tuner), hooked up the Comcast DTA, followed the instructions in this thread (thank you) and seemed to have it working fine changing channels. However, over the next couple of days on recorded material I would receive in the middle of the TV screen a large black box with the following message "One Moment Please" "Your service has been temporally interrupted" "It should be restored momentarily". That combined with having the picture freeze randomly during a recording (with the DTA channel notice appearing in the bottom right part of the TV screen).

I live in the SF Bay Area. I called Comcast technical support (is that an oxymoron?) and described this phenomena and could not get a straight answer out of them on two separate discussions. All they wanted to do is send service.

Anyone one else experience this? Maybe just a bad DTA, but I kind of doubt it. I also have a S3 with cable cards and no issues with signal strength (85%-96% on S3).

Thanks,

I live in Oregon and have been using a couple of DTA boxes for about 3 weeks now without any problems. But night before last, I also received that message on a Tivo recording that was made during the middle of the night. The message appeared in a black box in the middle of the screen.

I shrugged it off as just being a weak signal. But now I wonder if it's something else. :confused:

That message screen is somewhat misleading, but apparently the only one that an activated DTA can display when it encounters a problem.

I had that message appear a few times, but only one prolonged freeze. I've seen similar complaints elsewhere but it's hard to judge how common the problem is.

I would have first assumed that it was a poor signal quality issue, but I also have a full STB on the same outlet that has been flawless.

My feeling now is that the tuners in the DTAs are either substandard, or the units themselves are buggy. I invoked the diagnostic screen while the glitches were occurring, and the signal strength was within in the -4 range, with spikes to -6.

If this issue persists, I wouldn't hesitate to have them issue a replacement, or roll a truck. Forcing them into action (and incur cost) is going to speak much louder than a simple phone complaint.

JUST MAKE SURE YOU HAVE RG6 CABLE AND IT SOULD STOP. OR ITF YOU HAVE SPLITERS MAKE SURE YOU GET NEW ONES! THIS COULD LOWER THE SIGNAL AND CAUSE SIGNAL LOSS ALSO IF THE ARE OLD!

THE INTERUPTION IS DUE TO A LOW CABLE SIGNAL NOT SIGNAL STRENGHT OF THE TIVO. THE TIVO WILL SHOW HIGH STRENGHT BUT IN YOUR CABLE IT IS INTERMINTENLY LOW SIGNAL. IF YOU HAVE RG65 IT WILL NOT CARRY SOME OF THE NEW COMPRESSED SIGNAL. RG6 WILL SALVE IT!

As far as I know, a regular cablebox will solve the all digital signal problem except your Dual tuner will now become a single tuner, cannot hook up a DTA to Series2 that is using a cabel box as there is only one ir port on a tivo and even if you split that port, the chances that the cablebox and DTA having the same ir code would be slim to none

Thanks to the posters who explained how to enter the diagnostic screen for the Pace DTA.

My power level was between -13 to -14. According to a "tech" at Comcast the 'sweet spot' for these DTA's is +8 to -8.

I'm trying a amplifier/booster now as well.

I'll see how it goes before I venture behind my setup to the 'rats-nest' of wires, cables etc. to attempt to upgrade cable and splitters.

Hopefully if one can get the Pace DTA to the power levels suggested by Comcast the dreaded "One Moment Please" screen and the various freezing of the picture will go away.

I've read the entire thread and none of the suggestion make sense to me. I have a single channel Series two. I've connected the Cable from the wall to the DTA and from the DTA to Tivo's Cable in and then from Tivo's cable in to the TV.

However nothing I do will let me receive a signal from the DTA on my TIVO at all. I do not get any channels.

I've gone into guided setup twice. It asks me if I'm using a cable box (yes). It asks me if it's a digital box (yes). It asks me if it's Comcast (yes) It asks me what is on channel 30. (FOX sports NW - Yes). That's all it asks.

This forum talks about "advanced setup" and the ability to enter a special code and the ability to select what kind of cable box you have. My TIVO does not give me the ability to enter any of this information.

Therefor all the instructions are useless. Comcast has taken my lifetime service TIVO and turned it into a brick.

Therefor all the instructions are useless. Comcast has taken my lifetime service TIVO and turned it into a brick.

The first thing I would do is connect the DTA between the wall and the TV, with no Tivo involved. Once you connect the DTA, you need to activate it. For my area, I had the choice of activating over the web (via a browser), or via phone. The instructions that came with the DTA should tell you exactly what you need to do. You will need to set your TV to Channel 3 or 4, again depending on the instructions that came with the DTA. And note that activation can take several hours before the DTA is authorized.

Once this all works, and you can change channels using the DTA remote control (leaving your TV on channel 3 or 4), then you can start connecting the Tivo into the loop. It sounds like you did the right thing: Wall-to-DTA-to-Tivo-to-TV. Again, you will need to use channel 3 or 4 (based on the tivo switch), or you can use a composite video cable if your TV supports that (and set the TV to Line IN or whatever your correct setting is).

Now you need to connect the IR transmitter cable to the back of the Tivo, and set it so the two IT transmitters are an inch or two in front of the IR receiver on the DTA box. There are some sticky tape-like pads that come with it.

Finally, go through guided setup. When it asks you if Fox Sports is on channel 30 (or whatever), only say YES if you actually see that channel 30 is being displayed on the TV, and that it is in fact Fox Sports.

If this doesn't work for you, please be very specific about what steps you have followed, and exactly what you are seeing (or not seeing!). Hopefully I didn't leave out any critical steps!

Ok, I'll try that tomorrow. Also I posted in the Help section a question how to set up the dvt / tivo / TV, so that I can watch one channel on the normal inputs and on video 1, watch tivo playback and live TV. Right now having the the cable from the wall to DVT then to Tivo then to TV I'm getting the same channel on both.

Make the connections from the TiVo to the TV with an SVideo/composite video cable and red/white audio cable. You don't need a coax there at all.

Run a coax from DTA->Tivo RF IN,

That's it.

The TIVo will show you recorded content or Live video. Your choice on the TiVo remote.

That's the way I did had it before the box. When I tried it with out the coax I got static. Maybe the Pace/Comcast box shift thing will make a diff. I set my kid's Toshiba Tivo/DVD player (to Pace) and it worked great. I would have thought that the term " Comcast Digital Box" would have meant their "In Demand" HD box....

Hmmmm, I think I need to start all over .....I will give it a go tomorrow, bright an early.

Thanks for all of the help.

I read this thread and you guys had me worried. Comcast notified me that my area (Menlo Park, California) needed a DTA box. I ordered one and received a Pace DC50X.

Initially it wouldn't activate and I had to get a tech out to swap the box for another one. Par for the course with Comcast equipment.

Once activated I hooked it to my Tivo Series 2 and ran the Guided Setup. Everything went like it was supposed to and it works just like any other cable box. I am using the stock Tivo IR cable attached to the DTA just like you would with any cable box.

The Pace DC50X DOES work with the Tivo Series 2.

We have a house with 7 different cable outlets. We have 4 sd tivos one s3 tivo and 2 separate tvs. One with a digital box. We are preparing for the comcast switch and have decided to use the 2 free DTAs on one tv and one sd Tivo. My question is if we hook up the 2 dtas to the tv and tivo and activate them will that have any effect on the other sd tivos or only the dtas we activated. I don't want to give up the other tivos being able to get cable untill we have to. I was concerned because the instructions say to hook both up at the same time and activate them together.

It won't impact other cable outlets, or other boxes. In my case, I activated to DTAs via the web interface. When you go to activate them, you enter your id number, and the website "found" both boxes in it's DB and activated them both. There was no option to select only one of the two serial numbers, for example. I assume this is the reason that they want you to do them at the same time. I didn't try the by-phone activation method, but would guess it's the same.

On the other hand, I can almost guarantee that if you talked to an actual person in service, they could activate them individually.

The Tivos and 2 separate TV without a DTA or a regular cable box between them and the wall outlet will only be able to receive the channels that Comcast is keeping in its analog set -- something like channels 2 thru 32. In other words, you can only record channels 2 thru 32 on those Tivos without a DTA. However, on the one Tivo WITH a DTA, you can record and watch all of the channels in your purchased service, and, if your Tivos are all connected to you home's local area computer network, then you can transfer programs on the one Tivo-with-DTA to any of the other Tivos-without-DTA, for watching on the TVs connected to those other Tivos.

It turns out that when TiVo's IR blasters are placed directly over the DTA's IR receiver they grossly overload it. Even placing them six inches away doesn't work. But when placed three feet away or ten feet across the room they work fine!!!! Practically speaking, using a DTA's included IR extender is a better solution, but the mystery of controling Pace's DTA through its IR receiver has been solved.

Just popping in to add another Series 1 success... in large part due to the many notes in this thread. Currently using the standard 10104 code (as the -B option isn't available for the s1 anyway) listed under Comcast Digital Adapter, using 2 digit/fast/with 'enter'.
Actually, this was ultimately far less hassle then the cablecard setup for my S3. :D

In reference to the quoted, the only difficulty I ran into was initially with the channel changing - and after a bit of trial and error found that the remote receiver included in my set was faulty. No operation with either Tivo or the stock remote. After a few minutes of hate, found it worked without it and having the blasters set ~6 inches from the built-in receiver. No problems seen yet, so perhaps they've made some correction to recent boxes for this overload. In any case, clearly trying multiple blaster/receiver configurations should be done before calling the setup a bust.

Just to confirm again, the DTA does in fact output a standard BTSC stereo signal (was sometimes called MTS on consumer devices), so we're not quite stepping back all the way to 1985 equipment capability. ;)
(tho I'm having evil thoughts of opening the box to probe for baseband AV signals to tap before it gets modulated back out.)

edit: also add that the DTA sends CC through and Tivo seems to record & play such without errors, though I don't see a way to select what caption stream is used as source (not nearly as flexible as even the CECBs.) Probably only CC1/DTVCC1.
SAP is not available from the RF, so you don't want to set the Tivo audio options to use this. From the DTA remote though you can cycle through the available audio streams.

I have two series 2's with DTA's and the IR blasters are only a few inches from the front of the DTA and they seems to work fine. I did make sure they are DIRECTLY over the DTA eye which you may need to use a flash light to find and also the blasters are both pointing to the DTA eye. In other words the blasters are not in each others way both little "eyes" on the blasters can fully see the eye on the DTA.

I used the three digit way to change channels and I have had maybe one time on each DTA where lets say I wanted to record channel 044 but when I went to watch the show it has actually recorded channel 004 but this also has happened on my regular cable box. Seems to be very isolated and does not happen often.

I had a case or two of this "incorrect channel changing" also. Switching to the even slower speed C rating on my S2 solved the problem. There now is about a 3/4 second pause between each channel digit entry by the tivo when it invokes a channel change for the startup of a recording.

I've read the entire thread and none of the suggestion make sense to me. I have a single channel Series two. I've connected the Cable from the wall to the DTA and from the DTA to Tivo's Cable in and then from Tivo's cable in to the TV.

However nothing I do will let me receive a signal from the DTA on my TIVO at all. I do not get any channels.

I've gone into guided setup twice. It asks me if I'm using a cable box (yes). It asks me if it's a digital box (yes). It asks me if it's Comcast (yes) It asks me what is on channel 30. (FOX sports NW - Yes). That's all it asks.

This forum talks about "advanced setup" and the ability to enter a special code and the ability to select what kind of cable box you have. My TIVO does not give me the ability to enter any of this information.

Therefor all the instructions are useless. Comcast has taken my lifetime service TIVO and turned it into a brick.

If so, did you set the 3/4 switch to 3 and did you call to have the box activated? Does it work if you connect the box directly to the TV?

My DTA is indeed active, set to channel 3, and works when connected directly to my TV.

As the OP stated, he doesn't get the choice of Cable with box. He has to choose Cable, then "Yes" on the box choice, but it never asks which box, and what type of connection it sends out a signal with.

Did you try a re-boot then go through guided setup again? I was having a similar problem and reboot/guided setup seemed to work for me. The choice of box (Comcast DTA) is towards the end of guided setup, just before the IR testing.

I am having a problem entering 3 digit channel numbers. It seems to either not work at all, or change to the first two digits, or last two digits. Very random.

I have a few times already. Something's weird with Guided Setup -- it never asks me what brand/model my cable box is, even though I chose to use one. I may just give up and dig out the Moto cable box that Comcast provided a few years back and see if it'll work.

Comcast just switched channels 39-59 to digital in my area.
I am having a similar issue with the Comcast DTA tuning 3 digit channels.

I looked at the advanced options, the only possible options that looked worthwhile to tweak was the Enter option, but this is not needed if I am using the DTA's remote directly. Anyone figure out a workaround?

Hopefully, I don't need to use the 3 digits channels often.

BTW, the DTA is connected to my S2-540.
I moved the old GI STB to the S2DT since I trust the serial connection better than the IR blaster. I am thinking about replacing this one with a TivoHD.

I just found one of my DTAs to be stuck in one channel.

Channel change from the Tivo remote was unresponsive, so I thought that my cat somehow moved the IR blaster/receiver, but they were placed correctly. I used the DTA's remote to try to change channels, but that was not working either. I had to reboot the DTA by unplugging the power to make it work again.

My Tivo did record Tonight's show on Fri, but a few programs recorded this morning were the wrong channel.

Not sure how this happened, but it would be a coincidence to blame the DTV switch-over:)

Anyone experience such weirdness with the DTAs?

I have wrong channels record would say about 1% of the time or less. It has happened on two different DTA's as well as my cable box all using IR blaster's. BUT I have never actually had one "stick" on one channel where the remote was unresponsive.

Yeah, it was really weird to be stuck in one channel. Unlike a regular STB, you have no idea what channel the DTA is tuned on till you check liveTV. It was a fluke to discover it the following day since I was curious to see if DTA was able to tune to the free HBO channel (no) otherwise I probably have not discovered it for several days since the DTA is connected to a S2 that I rarely watch.

I have been using this DTA for about 3 weeks. I did a bit of a spot check of several random shows over the last few weeks, they appear to be ok. The DTA & Tivo are on a UPS so it could not have been a power failure. As I reported earlier, it does seem to act random at 3 digit channels, but I don't have any season passes with 3 digit channels. Quality control on these DTAs are probably not that stringent.

I also have a regular STB with a serial cable connection. It is an old big ugly black box but I don't think it has ever missed a channel change in about a year.

If it does not happen that often I would not worry about it. Like I said I have had it happen on two different DTA's and even on a full cable box. I know you can "tweak" the was TIVO changes the channels using the IR blasters but with me it seems to happen once of every 100 recordings if that.

I was also having the problem where my TiVo Series 2 Single Channel was able to make the Comcast Pace DC50X DTA box change to 2-digit channels OK but *failed* to change the channel to 3-digit channels. For me, the solution was to set the TiVo to "code 10104-B, 3 channel digits, no enter button," and the 3-digit problem went away.

Background:

How It Was Set Up When I Was Having the Problem
-----------------------------------------------
Based on a tip I had seen somewhere on the web but now can't locate, I set the TiVo to "code 10104-C, 3 channel digits, no enter button" and put all three IR emitters right in front of the DC50X IR receiver port as follows: TiVo IR #1 above the receiver port, TiVo IR #2 below the receiver port, and the DC50X extender to the left.

This was the best configuration I'd seen yet because I could reliably change to any 2-digit channel. However, anytime I tried to change to a 3-digit channel, the DTA gave up on waiting for the third digit and just ignored the whole command command before the TiVo sent out the 3rd digit.

So I changed to "code 10104-B, 3 channel digits, no enter button," and the 3-digit problem went away.

Additional Note 1: Comcast Pace DC50X DTA box randomly hangs: There is a separate problem with my Pace DC50X DTA box. I've discovered that randomly (after 7-10 days of working fine, typically), the Pace DC50X DTA box will fall into a mode where it ignores all channel change input and tunes to public access channel 27. When this happens, I have to power cycle the Pace DC50X DTA box, then the problem instantly disappears. I've now verified this sequence of events twice, so it's clearly a bug with the Pace DC50X DTA box (presumably hanging internally), not the TiVo. I'm debating whether to swap for a 2nd box or just try switching to AT&T Universal. ;-)

Additional Note 2: After this transition, my access to Science Channel (272) and NatG (273) has mysteriously disappeared. I'm assuming that Comcast has reorganized its offerings and put these in an even higher-priced package. Will take that up with Comcast tomorrow. ;-)

MANY, MANY thanks to all the people who have painstakingly contributed to this thread and sorted all these issues out!!!

I just verified that my code is already set to [10104-B]
I can sometimes manually tune to a 3-digit channel, but I just removed all 3-digit season pass programs. At least I have another Tivo to record these programs.

As far as the DTA freezing, it is good to get a confirmation from others experiencing the same problem. I don't think it has happened to me in the last week. Again, my solution was to move the season pass to another Tivo in case the DTA starts acting up again, but I am sure we are the isolated incidents so I am just going to stop worrying about the problem.

Just discovered last night that I'd been completely misinformed in my discussion a month ago with Comcast support. I'd called for clarification a month ago and been told that I should REPLACE my General Instrument set top box with the Pace DTA. Turns out that's completely incorrect.

As a better support rep explained last night, if you have a full-function STB, you don't need the DTA at all. DTAs are for freestanding TVs that lack their own full-function STB.

So I swapped out the DTA, swapped back in the STB, and everything is working fine again.

The IR receiver included with the DTA is optional, it's mainly only necessary if you need to put the DTA in a location where you would not have line of sight with the remote to the front of the box.

This is usually a result of a test of the public emergency broadcast system, they switch all digital equipment over to the test broadcast, I've seen several DTAs get stuck on C-Span afterwards. Might need a swap, might just see if it persists.

It may also be worthy of note that attaching the remote receiver disables the internal one. Found this out after I placed the new receiver in a plastic tube with the Tivo transmitter, and then the DTAs stock remote no longer worked unless shined directly into the tube, or I disconnected the remote receiver. Just something to be aware of.

FWIW, three months now with no DTA stuck-on-channel, nor other tuning issues yet on two S1 installations. If of interest, the DTAs operating information is:
Hardware version: 2
Firmware version: 1.466.2.1.2.1
Immutable firmware: 1_425_2_2/1_425_2_2
Bank A: GOOD PACEDC50X_0108
Bank B (active): GOOD PACEDC50X_0115

The second DTA is the same except for bank A/B, which is:
Bank A: GOOD PACEDC50X_0117
Bank B (active): GOOD PACEDC50X_0115

Maybe there's some faulty firmware out there... :confused:

I utterly hate these. Happens weekly, usually at prime time here. On my HD these often cause a hard crash of the Tivo forcing pull-the-plug reset if recording, and if not then all playback operations are locked out (no FF/REW/change channel/menu/etc.) Probably has something to do with changing the video encode type mid stream... e.g. a HD format to SD without a real channel change operation having been performed. :down::down:

The last two days I keep finding my DTA series 2 combo stuck on channel 26, the old channel guide channel.

Changing the channel with the Tivo or DTA remote does nothing. I end up power cycling the DTA and then I resync the two to channel two.

After that it works as before. Anyone have any info on this?

chakk
07-02-2009, 03:10 PM
Two possibilities come to my mind for your problem with the Comcast DTA hanging up on one channel after a few days of normal operation:

(1) your local TV provider has made changes (again!!!) to their digital channel lineup, and a power-cycle of the DTA is required to resync the DTA with the new lineup. The PBS station in the local SF Bay Area is advising their viewers to "rescan" their channel lineups regularly from now until mid-October, as they are expecting transmission frequency variations while they move their permanent transmitting antenna to a new location.

(2) The reception signal to your DTA provided over your cable is weak, and the DTA may be periodically losing sync. You can check the signal strength on your DTA by pressing and holding the INFO button on the DTA remote (with the TV turned on) until an information screen appears (this takes about 5 seconds of holding the INFO button down). Then, press the Channel UP button twice to view the third page of information. One of the listed items is named "Power Level". I read somewhere on this or another forum that the number shown here should ideally be between -8.0 and -4.0. If the number shown is less than -8.0, then your signal may be too weak. You could contact your TV signal provider for a fix, or, in my case, I purchased a signal amplifier from Radio Shack, which boosted my signal up from about -11.0 to -6.0. This solved my early problems with weak signal, although I suspect that enough other neighbor subscribers have complained to the provider that they have taken steps on their own to boost their signal strength in our neighborhood. So, I may have to turn down the amplification level on my Radio Shack box to avoid an overly strong signal, which could also create problems.

Hmmm interesting, I may change this setting if it happens again. Where exactly do you make this change?

Sorry to be so late in responding to this question to me, as I have been offline for several weeks while vacationing.

I made this change in the Tivo Main Menu -- Messages & Settings -- Settings -- Channels -- Channel Changing -- Advanced Setup.

At this point, you should see the 10104 on your screen. Just type each of those in again and then press the right arrow key and you should receive an option to select A, B, or C. A is the fastest simulated keypress, C is the slowest simulated keypress.

...!

Some of this has been said before, but a couple of things I found useful after I spent most of the weekend finally getting Tivo to work with the various Comcast digital boxes DC50X et al... (comments in the forum were very useful)

First - activate the comcast digital boxes before you try to make Tivo work. Otherwise, Tivo will give you some misleading error messages, like specifying that you should connect the DC50X to the Tivo using the composite cables, even though the DC50X doesn't support composite cables.

Second, as somebody else pointed out, the IR emitters need to be 4-5 inches in front of the DC50X box in order to work correctly. I used tongue depressors duct taped to the comcast DC50X box to support the IR emitters at the proper distance - looks like a kluge, but it works. BTW, the IR receiver is right next to the LED on the DC50X box.

By comparison, the Comcast Motorola box was much more straightforward - Emitters about 1 inch in front of the receptor - receptor is about 1/2 inch from message light - standard installation.

Since I had never needed the IR emitters before Comcast imposed the digital boxes, mine had long since disappeared. At least in the Atlanta area, no retail outlet carries the IR emitters; the clerk at Best Buy commented that people had been coming in all week looking for them. Rather than waiting the week to get them online for $12-15, I just bought a used Tivo on Craigslist for $40 bucks, giving me an additional remote as well.

That said, if I owned Tivo stock, I would short it - with all due respect to TIVOJERRY, when you spend most of the weekend struggling to connect two tivos, and end up with IR emitters duct-taped to tongue depressors, it's kind of laughable to read how Tivo thinks the IR emitters work great. Unless Tivo comes up with a 'game changer', Comcast DVR is going to drive Tivo out.

Back in June, I reported that one of my two DTA boxes would periodically hang: neither the Tivo nor it's own remote control could get it to change channels. This would happen once every week or two.

I replaced that DTA box the first week of July, so I've had the replacement a bit over a month now. So far, no issues. And the other DTA box has been flawless since day one.

so i just read this whole thread.

IIUC when comcast screws me completes the digital migration in my area, my 'box' input of my Series 2 Dual Tuner (S2DT) which is currently connected to a STB (Set Top Box) will be fine. But my 'cable' input, which gets the cable wire directly from the wall to the tivo (well, thru a splitter) ,and which currently records ch 2-99 using the tuner inside the tivo (no ir blaster nor serial cable) will only record ch 2-28 (or so).

The tivo site calls this "retain dual tuner capabilities" but they dont say "recording 1/3 as many channels as before". That seems misleading to me. I OFTEN am recording one channel 29-500 and viewing another 29-99, or recording two channels, one 29-500 and one 29-99.

So for the most part, my Dual Tuner is becoming a Single Tuner. Many people/posters have said that, and those ppl seem honest to me.

so...

here's an idea. I figured if this exists, the ppl here are likely to know abt it.

Couldnt there be a box that takes the cable from the wall as input, with digital only extended basic ch 28-99 and converts ALL those channels to analog and outputs them on another coax in analog form. Why do all the boxes 'tune' a single digital channel and output only that channel Why can't it tune ALL of them and output them all.

Cuz then i could just plug that right into my 'cable' input of my S2DT and i'd be happy.

does such a thing exist?

could it?

Sure, if you want to spend $50,000 building a cable plant in your basement.

I use one digit and no 'enter' with fair success, but on occasion, usually overnight, TiVo loses the DTA's output. Scrolling one channel up or down brings it back. I'm still troubleshooting the problem. It may be caused when a Teleworld Paid Program is recorded and TiVo attempts to return to the previous channel it was tuned to.


Have you gotten to the bottom of this? I've recently taken posession of the Comcast DTA. Though I'm not using TiVO, I am using a DVR (an EyeTV) with an IRBlaster (ZephIR). I'm having the same issue. It seems to occur every couple of days. Use of the Comcast remote to change channels brings back functionality. I am not recording paid programs. I can't figure out the cause of this for the life of me. I have emails out to both Pace and Comcast, but don't have high hopes. VERY frustrating.

I just spent the better part of an hour on the phone with Comcast.

I own a Humax Series 2 single tuner and I connect without a cable box.

There is no IR receptor on the side of the DTA as shown in the support pages of Tivo and using the front IR receptor is not reliable.

What I was told by Comcast was that I could get a cable box but since I already had cable cards, I would have to pay $5.99 per month.

This is highway robbery. So at the end of September I will get less service for the same money.

The hilarity of all this is I received a call from a local technician. He actually wondered outloud if you used a double ended mini plug from IR to IR if that would work. He was going to try and call me today.

In the meantime I received an email from Comcast ecare (supposedly their top notch customer service reps). In that email they said the DTA would not work with TIVO and there was NO Way that the Tivo could change the channel on the DTA.

I have responded with the link to their own web site citing the reference and telling ecare that they are wrong. Will see if I get a response.

Fighting with Comcast is a game for me. And I feel like the Energizer Bunny, I just keep going and going.

So today is a waiting game - will I get a call and will I get an email?

By the way - beware of that free box. I had a free box for a year but then they audited the acocunts and they made me turn it in. Make sure you get it in writing that the box is free.

LINK (http://www.lightreading.com/document.asp?doc_id=180850&site=cdn)

Essentially, the FCC has approved the use of embedded (low-grade) security in low-cost QAM tuners issued by cable companies to serve the needs of expanded basic cable consumers. The FCC evidently feels that many subscribers will benefit from greater low-cost access to advanced services through the availability of a less expensive converter box. (No one really benefits from forcing cable companies and cable subscribers to use higher-cost STBs for expanded basic cable networks.)

This waiver helps level the regulatory playing field, a small amount at least, between cable and satellite, which has been biased in satellite's favor for many years.

There is a down-side for some subscribers though: Cable companies have been considering a few options in the absence of the waiver. The temporary intention seems to generally be to rely on traps to secure the first level of advanced services (often called "expanded", including networks such as Disney, A&E, USA, FX, TNT, etc.) Traps are expensive to maintain, and therefore represent a significant cost of service, but the up-side of traps for consumers is that once you purchase access to a channel, you can receive that channel on every television in your home, with a tuner capable of tuning it in. With this waiver, the need for traps is relieved; instead that first level of advanced services can be secured with the DTA's privacy mode, which can be enabled and monitored remotely, representing much less cost. However, it means that QAM tuners without CableCARDs are unable to tune in these channels.

Despite this waiver, CableCARD still remains the means by which the industry complies with the federally-mandated requirement to allow consumers to use their own host devices. When considering the value of a QAM tuner a customer may own or purchase, whether it is stand-alone, embedded in a television, DVR, or PC card, a customer must always consider that the promise that that QAM tuner will work is limited to one signal service from each local broadcaster (and not necessarily the main-channel HD service), unless the QAM tuner is CableCARD capable and a CableCARD is installed and paired.

The haven't rescinded it. They waived it for specific services, for specific devices.

It's a tough balance that the FCC has to achieve. In the end, many people will benefit from getting expanded basic service on one of their two included ("free") DTAs, instead of having to pay extra for a STB. This is one of those cases where more advanced users have to defer to the needs of the overwhelmingly large group of less advanced users.

If you are changing a channel with the Tivo remote, but the DTA is not switching to the new channel, then either your IR blasters have slipped and are no longer correctly providing signal to the DTA, or the channel you are attempting to switch to on the DTA is no longer on the air (in which case the DTA stays where it was rather than go to a blank channel), or the DTA itself has failed and should be returned to sender for a replacement.

If this happens for every channel number you choose with your Tivo remote, then the problem is with the first or third option listed above. If this happens for only some (or one?) channel, I would suggest unplugging the DTA for 30 seconds, then plug it back in so it can re-sync the channel lineup with your service provider.

In earlier cable boxes (analog) it was possible to have both unscrambled channels carried along with ones the box had to be programmed to unscramble for THAT household.

Don't tell me the same can't be done with current boxes.

If Comcast and others wanted to, they could continue to provide ("expanded") basic channels unscrambled, along with other channels that need to be unscrambled on a per household basis.

This desire to use the DTAs as full-fledged cable boxes in no way messes with anything. The standard cable channels could still be provided in an unscrambled form, tunable by the DTAs or QAM tuners.

There is no question that some channels can remain in the clear, and we know that that indeed will be the case since at least one signal from each local broadcast station must be carried that way.

There is way too much value being provided to not employ a means of securing that value. So the only question left is whether that will mean that everyone will have to pay to rent a STB on every television, or pay only one third as much to have a DTA on every television.

They currently are for me. It's just the channels are hard to figure out:

You can still use your TV if it has a QAM tuner, just need to make a chart of the channels.

I've also been investigating this the last few days. Getting Comcast Technical Support to give me a straight answer is like pulling teeth.

I hooked up the Coax from Comcast to (2) different Tuners that are DIGITAL-ONLY, and NO Channels were received.

Then I hooked up an ANALOG Tuner to their DTA, and received Channel 3. I then used the DTA Remote to scroll thru the Channels.

I have concluded Comcast is sending a signal down the cables that no Digital Tuner can use. And that you must use their DTA and an Analog TV.

first of all, cable is a monopoly, they abuse that monopoly power. Totally incorrect. The US Court of Appeals recently spanked the FCC for making the same mistake you have, i.e., refusing to recognize satellite service providers are effective competition for cable service providers. So you're in good company in your error.

secondly, the tech exists, via cable cards or tru2way cards, to allow the cable company to secure their signal while at the same time not require the customer to use their damn boxes, which they FORCE you to rent and don't offer to sell! amazing they get away with that.What are you talking about? They do secure their service using CableCARD, and folks are indeed allowed to use their own CableCARD-compatible boxes instead of one rented from the cable company. I know: I have a TiVo S3 and it works great!

Beyond that, what makes you think cable companies are allowed to sell these boxes? They don't make them. They purchase them under contract from companies like Motorola, Cisco, Thompson, Pace, Samsung, etc. It is up to those companies whether or not to allow their boxes to be sold to the general public. These consumer electronics manufacturers have made it very clear from their own actions that they have absolutely no interest in doing business with folks like us.

Finally, it was the FCC who granted this waiver. This isn't a loophole. It's not a mistake or an oversight or an exploit. It was a deliberate decision by an agency that is traditionally very anti-cable. They even impose regulations on cable that they waive for satellite providers -- that's just how much they work against cable. They granted this waiver because it is good for subscribers. It provides a lower cost solution than requiring a CableCARD-compatible box for all cable channels, once they're all encrypted.

thirdly, lots of older people simply can't keep up with or understand all these changes. it simply isn't fair to them.There is no merit in your accuastion in that regard.

I've read the entire thread and none of the suggestion make sense to me. I have a single channel Series two. I've connected the Cable from the wall to the DTA and from the DTA to Tivo's Cable in and then from Tivo's cable in to the TV.

However nothing I do will let me receive a signal from the DTA on my TIVO at all. I do not get any channels.

I've gone into guided setup twice. It asks me if I'm using a cable box (yes). It asks me if it's a digital box (yes). It asks me if it's Comcast (yes) It asks me what is on channel 30. (FOX sports NW - Yes). That's all it asks.

This forum talks about "advanced setup" and the ability to enter a special code and the ability to select what kind of cable box you have. My TIVO does not give me the ability to enter any of this information.

Therefor all the instructions are useless. Comcast has taken my lifetime service TIVO and turned it into a brick.

The first thing I would do is connect the DTA between the wall and the TV, with no Tivo involved. Once you connect the DTA, you need to activate it. For my area, I had the choice of activating over the web (via a browser), or via phone. The instructions that came with the DTA should tell you exactly what you need to do. You will need to set your TV to Channel 3 or 4, again depending on the instructions that came with the DTA. And note that activation can take several hours before the DTA is authorized.

Once this all works, and you can change channels using the DTA remote control (leaving your TV on channel 3 or 4), then you can start connecting the Tivo into the loop. It sounds like you did the right thing: Wall-to-DTA-to-Tivo-to-TV. Again, you will need to use channel 3 or 4 (based on the tivo switch), or you can use a composite video cable if your TV supports that (and set the TV to Line IN or whatever your correct setting is).

Now you need to connect the IR transmitter cable to the back of the Tivo, and set it so the two IT transmitters are an inch or two in front of the IR receiver on the DTA box. There are some sticky tape-like pads that come with it.

Finally, go through guided setup. When it asks you if Fox Sports is on channel 30 (or whatever), only say YES if you actually see that channel 30 is being displayed on the TV, and that it is in fact Fox Sports.

If this doesn't work for you, please be very specific about what steps you have followed, and exactly what you are seeing (or not seeing!). Hopefully I didn't leave out any critical steps!

Hey. I'm having the same problem that mickpegg had. I know that my DTA box is working because if I plug its output directly into my TV, the DTA box works fine. However, when I plug the DTA box's output into the TiVo's RF input and run Guided Setup, all goes well until the TiVo box asks me if I can see video - all I see is a black screen.

How have people who had this problem solved it? Thanks much.

Get the DTA working on the TV itself (as some have done here), and have the TiVo setup for normal direct tuning (redo guided setup if you have a non-working TiVo setup right now).

Then, before running guided setup, connect the DTA to the RF input of the TiVo. Tune the TiVo to channel 3 (or 4, depending on how you have things set up - make sure the DTA and TiVo agree on either 3 or 4!). You should now be getting a signal from the DTA, and be able to change channels and see it on the TV by using the DTA remote itself (you have to keep the TiVo channel fixed on 3 or 4).

Only once you've tested you're getting all the channels you need through the DTA, then run guided setup on the TiVo. The purpose of the guided setup is to tell the TiVo how to control the DTA box, and that channel changes on the TiVo remote should not change the channel that the TiVo gets things on, but should just be passed on to the DTA box by the IR emitter (and to get the new DTA channel list)

12-13-2009, 10:41 AM
I appreciate the reply, but I've already done everything you said and when I get to the part of Guided Setup where it says "your channels are all set up. Are you seeing video now?", all I see is a black screen. Anyone else?

So you're saying that right before you're running "Guided Setup", the DTA signal is going through the TiVo, and you can see all DTA channels on your TV (though you have to use the DTA remote to do it)? And the back of the TiVo 3/4 switch is set to the proper one that the DTA is outputting?

If you're now getting a black screen, try changing the DTA channel with the DTA remote again, just to confirm everything is still working (you should be able to get all channels again, unless the 3/4 switch is wrong). The only two scenarios that should result in a black screen now are
1. the TiVo tuning the DTA to some non-existent channel (like 0), in which case the issue is getting the IR blaster to communicate properly.
2. The 3/4 switch is not set or functioning correctly and the TiVo is trying to read the signal on the wrong channel. Using the TiVo remote to change to the other one might work, I don't know. If you have the option, change both the TiVo and the DTA to use the other channel.

I solved the problem.

During Guided Setup, the TiVo box asks you if you receive any premium channels. Until now, I answered "yes", since I receive HBO and Encore as part of my cable package used by my HDTV in another room. Apparently, doing that sends the TiVo tuner into Deep Space, and it won't tune any analog channels at all (I tested this by plugging my cable directly into the TiVo box's RF input after Guided Setup completed, and I couldn't tune a single channel). It also causes Guided Setup to not ask you what type of cable box you have, or to even try to change the channels on the box.

Answering "no" to the "do you receive any premium channels" question fixes everything. Hopefully this knowledge will help someone else down the road.
