I have FiOS i the Northern VA area with 4 tivo HD and one of their moto dvr's. All 4 tivos pixelate, the motorola DVR does not. Swapping cables between the moto and the Tivo yields the same results, moto is just fine, tivo pixelates.

Do not have 9.1 yet, just signed up for the priority list, we'll see what happens. However, at least for me, the problem is bad enough to where any HD show I record off the fios channels are pretty much unwatchable as pixelation occurs every 2-3 seconds. The odd part is a reboot fixes the issue for about 24 hours, but obviously thats not a solution.

Got my fingers crossed that 9.1 fixes the issue, though all the 9.1 bug threads make me wish I had only signed up one tivo for the priority update.

I'm not sure what's worse - pixelization or dead tuners! I have fios and will stick with the crappy moto with the unbelievably crappy 2.0 interface until tivo gets their $#@! together. At least there's no pixelization or dead tuners and I can keep $550 in my pocket.

What's happening lately with all these hd dvr problems???

Wierd.....

You have FiOS 2.0 and you think that's crappy?!

From pictures and reviews I've read it looks fantastic. Better than ANY cable company box I've ever seen or used.

You want crappy? Try what we have here. It's ancient and it runs on ancient hardware. But if you love purple, it's great.



Consider yourself even lucky that you have FiOS as an option.

I have a Tivo HD and just got the "coveted 9.1" system update. The tech at the help desk guaranteed that an upgrade to 9.1 would cure my intermittent pixelation. Well... I thought it did initially, but it hits once and a while. Not as bad, but not gone. This is only occurring on my digital channels.

I was wondering if anyone else is still having problems?

Here is my config.

Verizon Fios.
2 Moto S-cable cards.

HD looks good, but not the digital.

I am having worse pixelation issues since 9.1 installed. Well, to be honest, I didn't have any issues with pixelation with 8.3.

I have:

Comcast in Jackson MS

Tivo S3 w/SA S-cards
Tivo HD w/SA S-cards

SA8300HD

For example, on NatGeo HD I have pixelation on both Tivos, but not on the SA8300HD. Since this has been going on all morning, I've been able to look at all three together.

The signal strength on the HD shows varying from 88 (pix starts) to 99 (pix ends at about 92). A couple of times it slipped to 77 and the picture froze.

The signal strength on the S3 varies from 87 (pix starts) to 100 (pix ends at about 91). A couple of times it dipped to 70 and the picture froze, and once to 50 and the screen turned gray. Also, periodically, I get the CC host ID screen indicating that my cards are not authorized.

Also, I get audio dropouts with any pixelation.

Also, I've tuned the same station with both cards and get pixelation on both, although it occurs MUCH more frequently with the card in slot 2.


On the SA8300HD, I get no change in the signal strength.

Not sure if I posted this or not so I apologize if this is a duplicate.

I had problems pixelation on my S3 tivo for a while. Cox cable with 2 Moto cable cards. Trouble was contributed to work being done in the area for a while, then not enough signal strength at last I was getting too much signal. Had at lease 10 calls for Cox to come out.

I had the same problems with the signal jumping all over the place from 94 to 70 to 0. Pixelation on both cable cards and near the end it would only do it on one. Thought there was a problem with that one cable card but they replaced it and I had the same problems.

Last tech to come out checked the signal strength coming in my house and found it to be WAY too high. He told me that normal signal strength was something like 6db +/- 3db. I had 18-20db coming in prior to my cable going into a 11db amp. Tech said that I had too much without the amp and put a device in to actually knock the signal down to tolerable levels. Haven't had one pixelation problem since. Everything works great.

Hope this helps.

Do you know what they bumped it down to? I don't know if they told me what my db is, but they did say something about 8... That could probably be this. I only have problems with my digital channels though, not my HD. Could this be the problem?

I want to say it was knocked down into the 9 range. I was having problems on the HD channels though not the digital channels.

Like so many people, I've been having the 3-4 second sound/audio freeze 5-10 times an hour problem with my Series 3 ever since the summer software update. The only difference with 9.1 is that the freezups are now papered over by a "fast forward" effect. I also had the "cablecard lost all the digital channels" issue after 9.1 was installed.

Thinking this latter was a cablecard issue, I got a service call from TimeWarner Cable -- and because I'd had them in to try and fix the pixelation issues several times before, this time they unchained their top guy from his usual post defending the headend and sent him off to see what was going on.

The cablecard issue resolved pretty quickly - we tried removing and reinserting the card, and the channels came back immediately.

The tech (hereinafter, "Deep Cable") then spent a lot of time trying to narrow down the pixilation issues. He tested the incoming signal out the wazoo, and took the time to show me, in depth, why the signal was good, going deep into the menus of his tester, etc.

After confirming that my signal was nice and juicy, and 36db s/n, we watched for the problem, and it was still there. He was a bit annoyed by the FF effect TiVo has apparently added, because it did not let him see the actual pixelation - hey, TiVo guys who are not officially allowed to read this forum, make that a selectable option!!!

We even watched his test meter for 10 minutes while it was checking both the raw and corrected bit error rates, both reading as <10-9 IIRC (ie: <1 error per gigabit).

We checked the TiVo signal strength reading, and it was coming in at 87-92 depending on channel. At this point, there was not much else he could do, so Deep Cable suggested I call TiVo support and get some suggestions, and he'd swing by later in the day if they came up with anything.

The call to TiVo tech support got a woman ("Deep Denial") who claimed that (a) she hadn't heard of the cablecard dropout problem and (b) she wasn't allowed to even consider the possibility of thinking about reading the posts on non-official forums. All she was able to do was (c) take down my report for posting in their tracking system and (d) repeatedly swear on a stack of TiVo manuals that I had to have a signal strength reading of 95 or better or the angels would weep for me.

I duly reported the words of Deep Denial to Deep Cable, and he popped back within the hour (within the hour -- did I mention he arrived at 9am for an "all day" appointment?) with a small amp to boost the signal going into the TiVo (there is already one at the house junction box, btw). But that quick test fix boosted the signal too much, so he went down the street to the junction there and ramped the signal level up and down while I reported the TiVo meter reading to him, and tweaked it until it was maxed - at 93-95.

The result, over the last couple of days, is that I'm still getting hits, but only 2-4 an hour, with some channels better (ie: 1 to 2 hits) than others. Of course, as soon as another tech even looks hard at the street box, it'll mess up again.

Deep Cable is of the opinion that the issue is inside the TiVo but that the only way to know for sure is to hook up another cablecard TV side by side and see if they have significantly different behaviors. But he told me to let him know if I found out anything more, or if there was a resolution to the issue from TiVo.

One final thing: in the TiVo diagnostics, when the tech's meter was showing 36db s/n, a line in the listing was showing TUNER 1 as having a SNR of 36db and the two cablecards as having (IIRC) an "OOB SNR" of 26db. Deep Denial said that her recently updated listings of the diagnostic screen did not show this line! Significant? If they are measuring the same thing, then a 10db difference is non-trivial!

Anway, that's what I know so far - and I hope they clone Deep Cable so he can be available to help each of you.

Nice writeup, thanks. OOB stands for Out of Band, or the separate frequency that the cable card responds to for channel authorizations, channel lists, etc.

I would be concerned with the lower DB reading only if your cable cards routinely lost authorization, etc. It's not related to the dropouts, AFAIK.

fyi, I got my first taste of the audio drop - fast forward weirdness last night, and I find it less annoying than the V8.x's pixelization fireworks, but still indefensible.

While I'm glad not to have the other issues others have noticed with the 9.1 upload, I have definitely gotten quite a bit of pixelation.

I've got an S3 w/ Wide Open West in Royal Oak, MI, 2 SA cards. 750 GB external HD hooked up via eSATA (working perfectly). Pixelation appears to occur on predominantly HD prime-time shows, both OTA and cable-based.
Also have WOW's HD DVR, which is a piece of garbage, and on which we've seen pixelation once or twice, but not nearly as often as on the S3.

I hope they can square this away soon. Quite frustrating in the face of an upgrade which brought no functionality I really wanted or needed.

An update - I was initially getting the "black Live TV - no TiVo background - cured by reboot" problem, but ever since I re-ran Guided Setup after the last reboot 5 days ago, I have not seen the problem, even with all kinds of switching tuners and jumping around menus.

I never had the pixelation and still don't. I think that problem is signal-related, or SA card signal sensitivity.

So, for those still getting the black screen, try repeating Guided Setup. Maybe it was choking trying to load corrupt Guide data or something - this is still at the superstition stage as far as thinking some action we took cured it...

And for those with the pixelation, check your signal strength with the Settings/Channels/Signal Strength feature. I get 100% on all the 1-99 channels and 98% on MOST of the HD channels, but they all come in OK. Take splitters out and test the full signal.

We've had some pixelation here (RCN in Montgomery County, MD, using a single M-card). I can't detect any rhyme or reason as to why it is occuring. It occurs for thirty seconds max in most of the recordings (usually hour-long shows). Our software is at 9.1 on the TiVoHD; it almost seems like the pixelation got worst with 9.1; we barely had any with the previous software (although, that was also pre-digital cable, so we were using standard cable and antenna and had pixelation via that).

how widespread is this?

i've been following this thread for several weeks, and have avoided purchasing an S3 because of all the reported pixelation problems. is there any sense of how widespread this is? i realize people posting to this forum represent a skewed sampling of all S3 owners.. but how can we tell if its 80% of people have pixelation or 10%? i have FIOS TV, and the new IMG is a total buggy POS!

can we do a poll on this forum some now? maybe the forum admin can help?

Pixilation As Well

Well, I guess I can put myself on the list of Pixelation and FF Wierdness.
Here is the thing - it seems to only be a couple of channels on FIOS in Mass. Channel 4 and TNT. The others seem fine.

Now, here is the kicker - I had Comcast until a few days ago. The pixelation and FF wierdness covered about 15 channels. 2 months before that, I had RCN - I do not remember a single incident with RCN (other than their hugely expensive service).

So, is this a provider issue, a Tivo issue, or a bit of both?

I can only speak for myself in saying I notice this problem only on second teir digital stations, provided by Time Warner, I.E. Speed, VS, and the provided HD stations. These are channel numbers above 200, channels below 200 do not have this problem.

I record locals via OTA with no problems.

The problem has changed since the 9.1 upgrade, not seeing pixelazation as much and the sound does not completely drop out.

My opinion is the pixel problem is either band width or buffering... I say this based only on observations before and after the TiVo upgrade to 9.1.

In other threads, some people have reported that 9.2 eliminates some pixelization issues with 9.1. Be sure to sign up for it @ http://www.tivo.com/priority/.

Everyone should get 9.2 within the next month, but if you can get it by Wednesday if you sign up.

Pixelization and lost channels

I never had the pixelation and still don't. I think that problem is signal-related, or SA card signal sensitivity.
I have had occasional pixelization on various channels since 1990, and I definitely had it at some level on the SA 8300HD. I still get it on my Series I attached to a standard SA set top. Qualitatively I would say my 2 Series III receivers do not have any greater amount of pixelization than the 8300 or the SA set top do. I have not noticed any greater amount in general under 9.1 than under 8.3. I definitely do have issues with a lost CableCard fixed by reboot since the push of 9.1, but note it sometimes takes 2 or 3 days or more for the problem to re-occur. When it does, the affected CableCard returns no video on any digital channel. Analog channels do not pass through the CableCards, and as such are not affected no matter what.

New Tivo HD pixellation with 8.1.7 software - fixed by restart

Just had a Comcast M-CARD Cablecard installed in my new Tivo HD today, and discovered this pixellation trouble as soon as I watched my first HD programming. Live TV is fine, but watching from a recording or the buffer has lots of pixellation and brief audio stuttered.

Initially thought my cable signal was bad, but I rarely had trouble with the Motorola 6412 DVR I am replacing. Signal quality is in the 93-100 range, and the S/N ratio on the cable input is over 35.

I signed up for a priority push of the new 9.2 software, but interestingly the problem disappeared before receiving the update after a simple system restart. The only thing I can think of that may have affected the system was that I aborted the Tivo startup movie sequence (by pushing the TiVo button) when the cable installer was present - could that have caused glitches?

Boy that sure looks like what I had to endure with BrightHouse here...

The broadband service ain't nuttin to brag about either...

I'm paying for 10 MB downstream... on a good day I get 4 MB... geeze

Just discovered this forum, and quickly learned that the version of the TiVo software that came with my box - 8.1.7 - may be to blame. I contacted TiVo support tonight, and they are promising me a priority update.

So I bought a new Tivo HD from Best Buy (had some gift cards to use) Sunday. Fios tech came out Monday and switched out the Motorola box for two cable cards (I don't know who makes them, I wasn't there for the installation). I got home, redid the guided setup, and started surfing. Right away I saw the pixelation / macroblocking on ESPN HD and TNT HD. It would be awful for ten minutes and then all but go away for a little while. Strangely enough I didn't see it on WRC's/NBC's HD. I was running 8.1.7c2-01-2-652.9.1.

I researched the issue yesterday and found many other sufferers. I jumped on the priority upgrade page, signed up, and last night got 9.1-01-2-652 installed. I rebooted and checked out the digital channels again. Much to my dismay I saw the problem was still there.

About an hour after that reboot I went to diagnostics and wrote down these numbers:

Tuner 0
Sig str 100 (never changed)
SNR 38 dB
RS Uncorrected 671
RS Corrected 263
Time since signal lock 1700 seconds (and counting)
CableCARD 1


Tuner 1
Sig str 50-100 (lots of flux, generally in the 60s and 70s)
SNR 30-35 dB fluctuating
RS Uncorrected 13285
RS Corrected 414004
Time since signal lock 320 (and counting)
CableCARD 2


Any ideas here guys? Is it likely a bad card? When I saw this the other night, pre update, and looked at the diagnostics, I thought I saw the issue on both tuners but maybe I didn't. Do the numbers I have here indicate one possible cause over another?

i had the fios dvr for 10 days and there was some pixelation occasionally, so when i switched to tivohd, i thought it was just fios. but last night i hit the tivo button and the main menu shows up all pixelated! obviously, not fios. no audio dropouts, and honestly it doesnt bother me much, compared to the stuttering problem i had with 9.1 and my tv's stuttering problem which was recently fixed. i feel blessed to only have video pixelation!
signal strength is always 100 from what i've seen

espnhd is the worst, seems the lower half of the video is almost out of sync...watched some poker and slow framed and when they switched cameras, a couple frames later, the previous camera frames shows up almost exactly 50% of the screen image and lower, only for 2 frames or so.

other channels are not this bad at all. i'm confident it will be worked out in the future either by fios or tivo

There have long been reports about ESPN HD having problems, but pixelated menus are NOT just a "bug". If you're seeing that something is wrong. If it continues you should get on the phone w/TiVo...it probably will not get better and could get worse. You may be entitled to a replacement either from TiVo or wherever you purchased your TiVo HD.

I had the same problem which was fixed by getting a replacement Tivo under warranty.

Take a channel on Tuner 1 which is giving you lots of RS errors and tune into it on Tuner 0. If you don't get the RS errors on Tuner 0 you probably have a tuner problem.

Looks Like Larry David might be experiencing the same problem...which leads to some other personal issues in LD's life...

Great find! I used to watch it but lost interest a while back. This one will be worth TiVoing for sure though!

Airs October 25th and 26th.

Schedule it:

The Tuner 0 numbers suggests tuner overload. Try attenuating the input. You could add a 4way splitter to the cable going to the Tivo.

It could also be a bad tuner. I suggest you try attenuation and then go from there.

Put myself back on the list as well.. I have 2 series 3 tivos 4 cable cards, both with the same issues.. I live in Chino Ca. with fios. Ive had it get bad in some hd channels ESPN HD and TNT HD and other hd channels in the 800s. sometimes its in the lower channels like 89 81 83 100 102 103. For a while it was only happening in the heat. now that its a little cool it still does it from time to time. Happening for 3 days and not happening again for a month.. I dont get it. its done it on all software ive had in it. I've had fios tech there and been on the phone with Tivo for hours even changing out one of my boxs. Whos problem is it? mine? Fios? Tivo? Sometimes it gets frusrating but. I deal with. I dont have much of a choice till something gets fixed.
