    It seems that many of us are convinced that 8.3 is somehow causing sustained pixelation and audio drops in machines that previously worked great or at least had very sporadic problems pre-8.3. I reported this to TiVo two weeks ago and the techs didn't even seem to know pixelation/audio drops were a frequent issue, so you can imagine I didn't get much help. Instead, they sent a new Series3 my way. It is working great but is still on 8.1 and I fear what will happen when 8.3 is rolled out to it.

    I know many others have already posted this issue in other threads, and it seemed like it was time to give the issue a separate discussion forum. Hopefully, TiVoPony will chime in at some point.

    I'd suggest checking your cablecards and your cableco's configuration of them. They are your interface to the cable signal and are responsible for probably 99% of signal related issues (as audio/video drops are) as I've seen and experienced. Also, get your cable company to check your signal strength and remove any splitters that you may be using. I highly doubt that Tivo's software is the root cause behind any signal issues.

    I'm not sure I would discount that so quickly. My evidence is somewhat anecdotal, but I feel that I've been getting more pixelation in the time since 8.3 appeared. It's not awful, but it is noticeable.

    Well audio and/or video dropping out or becoming garbled at times is different than simply slightly lower video quality or visible macroblocking as you describe. My point was that an issue where your audio and video both drop or become garbled at the same is very likely signal related and can be traced to the interface between you and the cableco.

    That's my experience, IJLT, and I am not a big believer in coincidence. Everything was fine for the first three months of ownership under 8.1, I then received 8.3 and major pixeilation/audio drops immediately followed. If I was alone, I'd buy the coicidence/other causes angle, but it sounds like many others are telling the same story. That's why I started the thread -- to share anecdotal stories to see if there really is a pattern. If so, I think TiVoPony will be interested.

    (I would appreciate it if the skeptics did not hijack this thread. I think most of us are well aware of the other possible causes. They have been discussed extensively in other threads.)

    I got 8.3 and have problems with pixilation and audio drop outs. It's not all the time though. I use analog cable and over the air only. No cable cards.

    I live in the same area as Runch Machine and have simular problems with pixilation and audio drop outs since version 8.3 was downloaded. It's not all the time. I have Comcast digital cable and over the air, with two cable cards. I had no problems before 8.3.

    Thank you for starting this thread. I believe it to be a very real potential problem and concern for many. This thread will allow us to compare and explore experiences. If I can find time for testing, I will definitely try to contribute my experiences but I fear I won't have time at the moment. My first test would be to record the same program OTA and over cable to see if dropouts occurred at the same time. If OTA HD and cable HD dropouts occur at the same time, we could probably rule out a bug in v8.3.1 and attribute it to satellite feed.

    Before I received my replacement TiVo last week, I had the opportunity to perform a test.

    A week ago last Thursday, I started watching the partially recorded first round of the Players Championship golf tournament from the beginning before the program had completed recording. It was almost unwatchable for the entire recorded portion -- a couple hours or so -- due to sustained audio drops and pixelation. Since the program -- a 7-hour marathon! -- had not completed recording I flipped it on live. I have my cable split such that one lead goes to TiVo, the other directly to the TV in case both TiVo tuners are recording and I want to watch a third show live. This gave me the chance to compare the live feed through TiVo vs. the live feed directly to the TV. The pixelation and audio drops were constant on the live feed through TiVo --just as they were on the recorded portion -- but the feed directly to the TV was a perfect picture. I realize this doesn't rule out faulty cable cards but suggests the signal from Cox Cable here in Gilbert, AZ was not the culprit.

    Did you have problems before 8.3 to the same degree you do now?

    I had MASSIVE problems with 8.0, which were maybe 80% fixed by 8.1. 8.3 isn't better or worse than 8.1 on my S3.

    I also had significant problems with 8.0 that were mostly solved with 8.1. Then 8.3 comes along and now things are worse than they have ever been.

    I have a Pioneer PDP-5070HD with a cablecard installed and I can switch to direct view on the Pioneer when I have problems on the Tivo. I have NEVER experienced any pixalation or audio dropout problems while viewing the Pioneer through its own cablecard. I have switched cable drops between the Tivo and the Pioneer with no effect.

    Cox cable has extensively checked my signal and replaced cables and connectors. My signal is very good as checked with their meter and consistantly shows 98-100 on the Tivo (except during pixalation events). During pixalation events the signal as measured by the Tivo jumps around from 0 - 100. However, the actual signal going in to the Tivo remains constantly good as measured by Cox. They also swapped cablecards which did not help.

    In my opinion, this problem is software related. Give me back 8.1.

    Has your Series 3 updated to 8.3 yet?

    I did not have audio drop outs or pixelation before getting 8.3. I am getting a lot of it now. I had it in the middle of the season finale of Heros! :mad:

    This seems to be a major issue, yet it seems to be effecting very few.

    I will be receiving a new box this week. I think I will leave it at 8.1 until these issues are ironed out.

    Not as of yesterday and I am having no pixelation or audio drops. I wish I could stay with 8.1 even though I know 8.3 did fix a few annoying things like slow program searches and the new 8.3 feature allowing HD-only programming searches is great.

    Doesn't the upgrade happen automatically, or can I block it?

    That's our setup and our experience exactly...no splitter, cable cards with Comcast. We had no problems prior to 8.3 and now we experience brief/sporadic pixelation and audio dropouts on our S3.

    If the first replacement box I received last week is any indication, it initially ended up at 8.1 after the guided setup.

    I assume after that, once it is available I can choose not to restart and stay at 8.1.
