    When I first got the Comcast DVR last year, I was having a lot of pixelation issues, and Comcast tested the signal and said it was too low (I have a 4 way splitter coming into the house, plus a 3 way for my home theatre set up), so they installed an amp and the pixelation issues went away.

    On my TiVo HD every channel I've tested get signal strength of 95 - 100, with the majority at 100. I had the tech test the signal before installing the M-CARD, and it was 12dB and 19dB from memory.

    I am confused! If 8.1.7b2 was just released, how is my HD running 8.3.1? Is it a matter of when the box was manufactured?

    I have not seen an update in several months, and I am not having any noticeable pixellation or blocking problems.

    You have the Tivo Series3.

    The Tivo Series3 got 8.1.x in February and 8.3.x in April. The version you have (8.3.1) is latest.

    Tivo began work on the TivoHD software in ~January, so they started with 8.1.x. The latest software for the TivoHD is 8.1.7b2. It doesn't yet have the performance and indexing improvements of 8.3.x on your Series3.

    Both the Series3 and TivoHD software platforms should merge with 8.4.x or 8.5.x late this year.

    B2 update, but still pixelation (perhaps a little better, but still not good enough to keep). Using SA PKM600 cards, circa 1Q06, OS Build: 2.3.149s2 (0) Mon May 2 2005 if it matters.
    No pixelation issues with the old SA 8300. Comcast of Palm Beach County, FL.

    Had an old pre-HD TiVo, and have been suffering with the 8300 UI for a year waiting for the TiVo HD option since going HD. Still within the 30 day purchase window, will be very sad to return it, but its not watchable in the current state.

    I'm keeping mine, because I don't care about cable cards. But if I were in your position I'd certainly return the box. TiVo needs to feel some financial pain here. They released what is a P.O.S. product for many people. There should be consequences to them. I desperately wanted this product, and so did many other people. But I wanted a *good* product, not something half-baked that was rushed out without any serious testing.

    Worse, they may have known about these problems ahead of time but released the product anyway.

    According to Tivo, they are now testing a pixelization fix for Scientific Atlanta CableCards for public release in a few weeks. The statement was posted last Tuesday so I suppose we could see that update released as early as next week.

    My TivoHD seems to be working a lot better with the new update. SDTV channels no longer pixelate/macroblock and my audio-dropout problems on Dolby-Digital have disappeared from SDTV as well. Yay!

    I did watch one HDTV program and I still had the audio dropouts/macroblocking. THOUGH this program was recorded pre-patch, if that matters... I think the dropouts were lessened, but still 5 or 6 times in the hour.

    My Tivo does crash (insta-reboot) when playing certain MP3 files from my computer. I can PM a bad file to anyone who wants to test. I can't really use the music playback anymore due to the reboots. I am not positive this problem is new to the patch because I didn't listen to music that much on the new Tivo HD. My old S2 boxes can play the file without any issue.

    This is all with dual Moto S-Cards with Time Warner.

    It does matter. :)

    The update appears to eliminate the random, non-signal-related pixelization on recordings made before the update is installed; this is the pixelization you would never see in the same spot twice. However, the signal-related pixelization is only eliminated on content recorded after the update was installed; this is the pixelization you would see in the same place with REW / REPLAY.

    The 8.7.1b2 update has new drivers for both the ATI QAM/ATSC demodulator and XCode OpenCable (CableCard) receiver chip.

    As you've probably gathered from other posts in this thread, the b2 update eliminated TivoHD-related pixelization issues with Motorola CableCards.

    The update cannot eliminate pixelization related to source encoding (i.e. overcompression), which is what you still see with the cable company's own STB / DVR. Nor does the update eliminate pixelization due to a poor signal, which can result from defective or split coax cabling, defective splitters, too many in-line splitters, or over-amplification.

    Customers with Scientific Atlanta CableCards are still waiting for their fix, which Tivo has said is now in testing for release in a few weeks.

    Oh I'm really hoping that's the case then... :)

    Though, all of the problems I had (have?) while watching HD streams isn't recorded on the drive. When I got the dropouts, I can just replay it and there was no blocking or audio dropouts. (The two were never related. I got audio dropouts with macroblocking and vice versa.)

    What I need to do is record some HD shows and watch them. KCET (PBS) here in Los Angeles airs unedited Warner Brother's movies on Fridays in HD -- so I should record that and watch it.

    Anyway, the fact that all the problems are gone from SDTV content (for me) is extremely pleasing! Thanks Tivo and keep up the hard work. I have faith these problems will all get ironed out.

    Nice supposition. Unfortunately, incorrect. :rolleyes:
    :eek: For someone in such a position, you sure jump to a lot of less-than-fact-based conclusions.
    Suppostion express, all aboard!
    Can I have your stuff?

    I’ve seen a few posts where people say that 8.1.7b2 has solved the micro blocking and pixelization issues for people with Motorola cards. THIS IS NOT TRUE. I have 2 Motorola S-Cards and 8.1.7b2 installed and I still get micro blocking and pixelization. The weird thing is the SD channels are the worst, to the point they are unwatchable. HD and digital channels are fine most of the time; unless something is recording then they start to have issues.

    The signal strength is at 100% but when it starts to pixelate it drops to 45-50%.

    HD Tivo
    2 Moto S-Cards
    Verizon Fios

    I did call customer support and they were very nice. After my initial call they called me back and ask for more details on my receiver which I was very surprised about. They said if the issue is not resolved by my 30 days they will extended it another 30 days. I'll stick it out until then. I still have my DirecTv Series 2 hooked up so I just flip over to that when the HD Tivo starts acting up.

    You should read the rest of the posts where it is acknowledged that this fixes SOME (but not all) problems, and that there is another fix in development.

    I'm one for whom the b2 update cleared up the macroblocking issues I was seeing with two single stream Motorola cards. There is definite progress, but I'm sure there is more than one issue at play making complete resolution a step wise progression. With the macroblocking solved (here), the machine is working wonderfully.

    Hang in there. This box is far better than the Comcast DVR which it emergently replaced after the iGuide update.

    Your issue has nothing to do with CableCards.

    Your signal level is inappropriate for the TivoHD. The tuner in the TivoHD is more sensitive than the tuner in the Motorola boxes. If your cable signal is too weak or too strong you will get constant pixelization with the TivoHD.

    From the ONT, Verizon puts out a cable signal that is "20 db hot." You've probably seen this mentioned on their commercials. "Hot" refers to the signal strength. They output such a strong signal from the ONT so older cabling and multiple in-line splitters don't cause problems. However, as is, the signal is generally too strong for the Tivo and pixelization can result.

    Signal levels vary somewhat depending on the make and model of your ONT.

    You need to have Verizon come out and adjust your signal levels so they are more appropriate for the Tivo. They should swap out the splitter and try your setup both with and without an attenuator. If you have another splitter lying around, you can also trying installing that in front of the TivoHD to see if that reduces the FiOS signal to a level the Tivo can handle.

    A signal range is in the 93-96 range is probably ideal with FiOS.

    My installer said I have one of the original ONT's. This older model has since been replaced for new installs. He said the signal coming out of my old ONT is something like +17db, whereas the newer ONT's are a little lower. He liked the fact that I had an old ONT because it gave him more leeway to adjust.

    My THD reports the signal strength at 100%.

    Since the latest software release that fixed a bunch of the Moto card issues, everything has appeared fine on my THD. But just within the last day or 2, I've noticed some brief "scrambles" on live or recorded content. Maybe once every couple hours, as opposed to once every 15 min. as it was before. But it looks the same.

    Not sure what this is, or why it has returned, or if it's even the same issue as the more frequent pixilation that I thought was fixed.

    Thanks. I haven't been keeping up, and didn't realize that new model had been released.
