Roamio Plus - Comcast - SNR/Signal Level

TiVoCommunity Forum Recent Threads - Mon, 09/16/2013 - 11:58
Not having any issues.....but after looking this morning to see if my Tivo rebooted last night (separate issue) from the DVR Diagnostics screen....I noticed all my my tuners had 100 signal level and generally a high 41-43 SNR.

Now after doing a bunch of reading online....seems Tivo recommends the following ranges:

Minimum SNR
QAM 64 - 23 dB
QAM 256 - 29 dB

Maximum SNR
QAM 64 - 30 dB
QAM 256 - 35 dB

Now, the only real reason I care is some people say those high levels of mine, not so much the SNR but the signal, can cause the Tivo problems over the long run. I've read somewhere that Tivo has protection built in that in extreme cases will cut the signal if it's too hot?

Most people I read say that Tivo is a little picky with the SNR numbers. Some say why would a high SNR be bad......only thing is that a high SNR could mean a high signal level (which I think is what I had).

My setup
For my house I have the cable that enters the house split once (-3.5dB each) to feed the cable modem on a clean run and the other to feed a 4 port amp that boosts (7dB) for each port. One of those ports feeds the Tivo (about a 26 foot run).

So first thing I did was take the split before the amp and split it again with a -3.5dB splitter. I fed the Tivo directly from this, and the amp with the other side. That was line into house -3.5dB, -3.5dB and then a run to the Tivo. This was OK....but overall I saw some issues with some channels having a real low SNR level of 26 and a low signal level. This caused severe pixelation and tons of errors.

So next I reverted everything back to the amp. From the amp port that feeds the Tivo....I ran a cable into a 3-way splitter and used one of the -7dB ports. This to me is basically using the amp to go +7dB and the splitter to go -7dB. This really didn't make much difference. All my signal levels stayed at 100 and the SNR levels stayed basically around 41-43dB. I read this as the signal was still to hot.

So I took that -7dB run and split it again with a -3.5dB splitter. Now, SNR levels down into the upper 30's (36-39dB)....but what I think is more important are the signal levels are now all under 100....most in the 96-99 range.

What's weird is by splitting this after the amp....I'm taking -10.5dB off the signal (while adding 7dB)....that technically is about the same as splitting the line before the amp....but for some reason splitting before the amp dropped the signals too much? No idea why.

Anyway.....I think I'll order some attenuators and replace my franken-splitter setup.

I'm assuming splitters do the same thing as an attenuator would correct? Just that the attenuator is a cleaner install?

Anyone know why the pre-amp split would cause the bad signal levels?


Roamio Plus - All tuners on same channel

Any idea why this morning, all 6 tuners on my Roamio Plus were tuned to the same channel?

It didn't reboot overnight as far as I know....the DVR Diagnostics Cable Card Time since OOB tune start was 146000 seconds.

Dexter S08E11 "Monkey In a Box" 2013-Sep-15

TiVoCommunity Forum Recent Threads - Mon, 09/16/2013 - 01:48
I was enjoying this episode until the last 5 minutes. And then the writers go and ruin it AGAIN by dumbing Dexter down and making a totally contrived situation. Sure, I get it that Dexter did not feel the need to kill Saxon. But nevertheless, killing Saxon was the only smart thing Dexter could possibly do. Saxon knows way too much to risk what he might say if he is arrested, even if Dexter is out of the country. I was expecting Dexter to say, "I don't need to kill you, but of course I will anyway."

And then there is Deb, she has the gun pointed right at Saxon from 10 feet away, while Saxon has the gun at his side. And yet Saxon manages to move his arm up and take a shot at Deb before she manages to move her trigger finger? Sheeesh.

A smaller issue, but still a symptom of the bad execution this show has had this season -- when Dexter was getting all traces of himself out of Vogel's apartment, opening all the drawers, going through the files, etc. -- he was not wearing gloves. Arghhh!

Hmmm, did The Newsroom suddenly become a fairy tale or a Disney movie? I cannot remember the last season finale -- for any show -- that had such a sappy, sweet ending.

I couldn't tell whether the Michigan call that Jim made early turned out being correct or not. Was that the final vote tally on the computer screen?

prepping a Series 2 for sale

TiVoCommunity Forum Recent Threads - Sun, 09/15/2013 - 22:43
I'm cleaning out the basement and would like to see if I can sell my unused Series 2.

Is it necessary and/or a good idea to clear out my stuff from it? Not even sure what is on it that may be an issue. It's name? my name? My network name? My network password? My telephone number? My Amazon Instant Video credentials? Is there a go-back-to-factory settings option? If there were, would that be what I want to do? If I am selling it with lifetime service, I wouldn't want to de-activate it, right? Or should the new buyer re-activate it?

If I did want to do something, how would I? I'm at a new location with a new Premier and new cable service. If I plug it in wouldn't it want to download programming?

a little confused...appreciate if anyone who has done this could shed some light

tivohd booting issue

TiVoCommunity Forum Recent Threads - Sun, 09/15/2013 - 22:22
I have a TiVo hd that is about 3 years old. Expanded to 1tb. It goes to the welcome starting up page and then the screen goes black and then back to welcome. I put in the old original drive and it booted without difficulty. The drive is a wd10ears. I did the windows dldiag program and no errors found. I tried to run wdidle3 1.04 and it just gave me a system error when I typed in wdidle3

Any suggestions?

I assume it is a bad drive. If so what is a good inexpensive 1tb drive to replace it with.


something as simple as VideoReDo

TiVoCommunity Forum Recent Threads - Sun, 09/15/2013 - 22:08
does anyone know of an app that's as easy to use, as fast and reliable as VideoReDo for quick edits? I've demoed the trial just to clip tops and tails, and then re-save in the same format. VRD is great at this.
I then use Handbrake to convert, as it as more options for audio tracks.
Is there an alternative app that can handle .ts files, TiVo, mpg2 etc for the raw editing part? $100 seems a little steep for that one purpose

I have a MP4 file as of right now. Any help would be awesome. I guess I need to know what format it needs to be, then how I would copy it to the TiVo?

FS: S2 DirecTV TiVo and extra drive

TiVoCommunity Forum Recent Threads - Sun, 09/15/2013 - 19:38
After almost a decade with DirecTV TiVos, I finally moved on to the Genie. I have my last working S2 DTivo listed on eBay. Since I cannot post links, search on eBay item number 331024115417.

This is a Samsung S4040R that I upgraded with an 80 GB drive. I'm also including a 40 GB drive (pulled from another one of my DTivos with bad tuners) to use as a spare. Both drives have 6.4a and are Zippered. Ethernet adapter included too. I also replaced the bad power supply capacitors. I'm hoping someone will give it a good home - other than having to fix the power supply it has served me well.

MVR with new Tivo does not work

TiVoCommunity Forum Recent Threads - Sun, 09/15/2013 - 17:16
I have a new TiVo premiere XL that I just connected but during the move a addition of the new TiVo I have lost the ability to do MVR. Here is what happened.

1) I initially wanted to use the old TiVo Premiere in the bedroom with just an OTA signal so I took the cablecard and tuning adapter and installed them in the new Premiere XL.

2) All looked good and I could browse the now playing list on the old TiVo on the New TiVo.

3) I decided I didn't like the old TiVo without the cablecard and so I got a CableCard and tuning adapter and installed them.

4) At some point before I realized that MVR wasn't working I changed both TiVo names. Later I changed them back because I thought that might be the problem.

5) I set up a TiVo Mini - that worked and still works

6) at some point after 5 I saw that MVR wasn't working on either TiVo - both boxes showed the other TiVo grayed out with an explanation point

7) I tried resets, reboots with no success. I then selected the option "I no longer have this TiVo" thinking that when it reappeared on the network it might trigger a new connection. - This may have been a big mistake, since then neither shows the other TiVo since. Checked ports, reset the router, and even reset the TiVo XL to 'clear and delete everything" since I had nothing to lose (the other TiVo has a lot of recordings so I can't do that without losing a lot of shows)

8) TiVo.com support said to force a new network connection and restart each TiVo - no joy

9) TiVo.com again went through a bunch of resets, changing settings etc... with no change.

10) Last option from TiVo.com was that the MoCA bridge was somehow keeping the TiVo's from seeing each other.

Both TiVo's can connect to the network (vis MoCA connections), I can use kmttg and pytivo with no problem, the TiVo Mini works.

Long post, but I'd appreciate some help as Tivo.com has given up

A way to set season pass defaults.

Please add a way to change the defaults in season pass. For instance a way for it to always default to the number of recordings to keep that you specify one time. Also please add a way to change distinguished passes globally for the number of recordings to keep, etc.

What are differences between a 652 and 658 (Series3)?

TiVoCommunity Forum Recent Threads - Sun, 09/15/2013 - 16:02
I have two (Series 3) TCD652160s that are working fine. I have a friend who might be giving me his TCD658000 due to it no longer working (probably either bad hard drive or bad power supply). I plan to try and revive it, but had a question concerning the two.

I think I know the main differences between the two. The TCD658000 come with the following (over the TCD652160);
  • a larger (1TB) stock hard drive
  • THX certified
  • has a glo remote

Are there any other major or minor differences between these two Series 3 TiVos? Or is this pretty much it?

Roamio Plus - audio blip with Video Window

TiVoCommunity Forum Recent Threads - Sun, 09/15/2013 - 15:06
Loving my Roamio Plus.....it's been great.

Curious if others have this happen as well......when you are watching live TV and press the Tivo button to go into the main menu.....does the audio drop for a second from the Video Window? Like it's not a completely seamless transition from live to the menu? The audio drops only for a second.

I don't get any audio drops when bringing up the Guide which also has the Video Window.

Not really an issue....just curious if it's something others see as well.


Tivo series 3 power supply & hard drive questions

TiVoCommunity Forum Recent Threads - Sun, 09/15/2013 - 15:04
I have a spare Series 3 TiVo (model TCD652160) that is not being used. It works fine, but has no subscription to it & just sitting in a closet. I might be getting a broken TCD658000 from a friend. They claim (& think) the hard drive is the issue.

I will pull the hard drive and run the WD extended test on it to see if it is truly the hard drive. If it's not the hard drive and rather the power supply, can I simply swap these two power supplies? I realize the Series 3 (OLED) can't be used in either one of these, but was wondering if the TCD658000 & TCD652160 use the same power supply since & are interchangeable since they look pretty much identical.

Now, if it is actually the hard drive that is the issue, can the 160GB hard drive from the TCD652160 be used in a the TCD658000?
