    I've been having this problem for at least a month now. Recorded & live video freezing up, both HD & SD. Rewinds sometimes prods it on, but eventually have to soft reset. That clears it up, but the problem comes back eventually. Using a 500gb Samsung drive internally.

    Interesting, we just started having the sound issues. It only happens through the home ent system though. If we use the audio on the TV only - no cut outs.

    I began experiencing the problem about two weeks ago, using two cable cards with Time Warner.

    For me, Standard Def seems be much more likely to trigger the freeze.

    Hi folks,

    Thanks for your patience. Our engineers are still investigating, and have asked me to post for more information.

    One important update: Please don't use the 7-7-7-Clear for anything other than a video freeze that fits the pattern described in this thread. Only TiVo HD units are experiencing this issue. If you have random freezes and jitters, or you have a Series3 unit, then you have a different issue and those should be posted in other threads.

    Please do not use that 7-7-7-Clear sequence if your unit is entirely locked up -- only if the problem is frozen video but an otherwise responsive unit with normal working menus.

    Below are some questions. Please post here in this thread in reply; don't e-mail individually since it just creates an extra step for me to then pass on the information to the engineers -- so it's faster for them to read it here. They are monitoring this thread.

    1. Does your video freeze ever happen in the middle of recording a show? If so, what happens after a reboot and you go back to play that recording and reach the point where the freeze occurred?

    2. When there is a video freeze, are the loopsets (the background animation in the menu screens) frozen also?

    3. If you are in live TV when the video freezes, what happens when you go into Now Playing and play back a previously recorded show? Have you ever seen a case where a previously recorded show played back normally despite live TV video being frozen at that time?

    Thanks again for your patience as we research this issue.

    Best regards,
    Stephen

    I have never had it freeze while I am watching it. My TV usually stays on the HD channels (which do not freeze unless I am coming from a frozen channel). I only get the freeze when I switch to a SD channel or I try to play a recording from a SD channel.

    I guess you are talking about the guide and the progress bar at the bottom. No they do not freeze. Only the actual picture is frozen. I can actually hit rewind and the video looks fine while rewinding, but when I stop to play I get audio for a little but picture freezes at exactly where I stop. So I wouldn't call it an actually freeze. Everything seems to work fine accept for the picture moving forward.

    I tried this from a channel that was frozen (my local news channel 9 on Comcast in Knoxville). I went to watch a recording of Lost (record from a HD channel) and Lost worked fine. Went back to live TV and it was still frozen. Pulled up other recordings and they worked fine. I had one recording that was recorded on a frozen channel today (it was in SD of course) and it was recorded frozen and unusable.

    So I guess I will say if it is recorded on a channel that is not frozen it will work fine no matter what live TV is doing.

    One thing I will add is this. Lets say I am watching ESPN HD and I go to a SD channel that is frozen, if I jump back to ESPN HD it will now be frozen. To fix it I have to move along the HD channels until I find one that is not frozen (it only takes 1 or 3 channels). Once I do all the HD channels work fine. Note this only happens if I come from a frozen SD channel.

    So I think this is a SD problem for me since my HD works fine as long as I do not go to the SD channels. I don't think it is a cable company issue (with me) since it looks perfect when I rewind on the frozen channel.

    Hope this helps. I am just glad most of main shows are off for 2 weeks and they are mostly in HD.

    Edit: & yes if I restart the system everything seems to work find for a little bit.

    1. I never actually see the freeze happening. It always seems to occur when the Tivo is not being used.

    2. It varies. When the freeze is in effect, sometimes the background animation is fine, sometimes it is sluggish. It never fully freezes though.

    3. (Per #1) I've never been watching live TV when the freeze kicks in. But in my case, both live TV and recorded shows are always affected at the same time. I've never seen a case where live TV is frozen yet recorded shows still play back fine.

    I've only seen the freeze problem after turning on the TV ... I've never seen it actually start. Also, I want to say that both times it's occurred recently, both tuners were recording (red LEDs on). It doesn't seem to affect recordings in progress (but trying to play back previous recordings from the NPL shows the same problem). Background loopsets seem to be fine.

    As another data point, I have the WD Expander attached.

    long...
    my tivo doesnt freeze, just the video on the screen freezes. rebooting the tivo fixes this problem for me but it seems like it happens once a day.

    EDIT* i have a tivoHD unit btw.

    I have witnessed the screen freeze while watching 20 minutes behind an hour long live show - using the recording not the live buffer. Every other time the freeze has happened while I was away from TiVo.

    The problem started with what appeared to be a stuttery quality to the video. I was in the midst of recording two programs (watching one of the two time shifted) and the first freeze occured. However, I was able to fast forward a second and hit play, and the video worked. It would then repeat, and I would hit fast forward and play, and again it worked. This must have happened 20 times during a 45 minute span, with each instance of the freeze happening closer to the last. Finally the shows finished recording and I restarted - and no more video problems that evening.

    During the usual freeze where it is frozen when I turn the tv on, I can fast forward and rewind, but when hitting play audio goes for a few seconds, and the picture freezes completely. Menus worked normally throughout, but all video is completely frozen. I didnt try playing other shows when the freeze occured.

    Had freeze issues over last 4-5 weeks. Reset always helps. Mean Time Between failure seems to be contracting unfortunately. Freezes on both occasions, when running prerecorded or time shifted. Have a MyDVR attached since Jan.

    However, another issue that may be connected with 9.3a upgrade...

    On a need to add a broadcast station to the list, I found just a single line entry 'Channel 0'. No scrolling would help. Intrigued, I forced a channel number (say 48), and there it was - the entire list. Adding the channel there didn't help the actual channel lineup. Forced new channel scan - unit went through the motions of a scan but sorry, same end result - single line Channel 0). Tuning for strength for channels on the list got me a message such as no channels available (strange just about when my channels on the list are recording....) To sum up...I cant add a channel ... a ticking issue since it can end up as no channels if the unit loses the 'original' list wherever it resides.

    Methinks, the problem is with the software where some data tables are left destitute after upgrade. I suspect the channel data is stored and mirrored in three or more locations - first is actual channel scan data download, another where this is ported to populate the list we see, another where this is passed on to the unit main program to identify valid channels for record/guide. I think the link is broken between second and the rest - new scan does not port to what we see or check, and that output does not update the internal table. On second thoughts, perhaps I should be thankful, because my unit atleast works with current lineup!

    Come on TiVo guys ... YOU are clever and can get this fixed...

    I know you guys are interested in TiVo HD feedback so I didn't send any logs, but my S3 just had some strange behavior.

    It was paused at the end of a show for about 5 minutes and all of a sudden it started macroblocking, dividing the screen into roughly 3 vertical panels, each doing their own macroblocking.

    The unit was otherwise functional and I could get to NPL, TiVo Menu, etc. (with no macroblocking)

    I used LiveTV to tune see what the 2 tuners were buffering and discovered that one channel, TNTHD (encrypted channel so CC is involved) looked like it was frozen with some macroblocking, and the other tuner was on some SD channel that was fine.

    I went back to NPL and played the same show and put in on pause in the same location. Video looked fine.

    I then went to my second S3 to see if it could receive TNTHD. All I got was a black screen when I tried to tune TNTHD (otherwise TiVo was functional). I could tune other channels, just not TNTHD.

    Still on my second S3, I then went to Menu->SystemInfo->Diagnostics and my S3 is hung on Please Wait. Background mpg is still running but the TiVo otherwise will not respond. I've seen this behavior before on S3s where they get hung on the diagnostic menu. I think it showed up in 9.1 and I thought it was fixed in 9.3 but it seems to be back. I'm wondering if that freeze (or attempts to fix that freeze) have anything to do with the TiVo HD frozen video problem.

    Anyway, as I pull the plug to reboot my second S3, I switch back to my first S3, and notice the macroblocking has started again, again, while I was paused at the end of a show.

    I tried entering the channel diagnostic screen (now on my first S3) and it worked. I notice TNTHD has 184299 RS uncorrected and 115419 RS corrected errors so that probably accounts for why I can't see it.

    I post all these symptoms in case any of them might be related or might trigger some other problem. Maybe there was some change in how error conditions (mpg, cablecard, etc.) were handled and that is causing some freeze. People who don't see any errors on their system don't invoke the problem code, but people who do get the freezing. Just random theories. Maybe my problem is totally unrelated.

    UPDATE: TNT-HD is now back and I'm not receiving any RS errors any more. Since TNT-HD has come back, I've also been unable to reproduce the macroblocking on paused playback of existing recording.

    I had this happened twice this week.

    1. Never happened while watching live TV. Only pre-recorded show are frozen, while they are frozen Live TV still plays fine.
    2. Did not notice the loopset, but will look next time.
    3. I have it the other way, Live TV plays, Recorded shows won't.

    1 - I don't watch live tv so I don't know. When it happens for me it is when I try to watch a show I've recorded or that is in the process of being recorded. A few seconds in it will freeze. I can fast forward and rewind and those look ok, but when I hit play it freezes again.

    2. I've never noticed if the loopsets are frozen or not. When it happens again I'll try to remember to check.

    3. Once it happens for me on one show it happens for anything I try to watch in my Now Playing list.

    Found my THD again in this state this evening so I did the 777-Clear. This was different though: switching tuners back and forth unfroze it. A little later (I had it playing in the background) it froze again, but swapping tuners unfroze it again.

    That tuner swap trick hadn't worked before.

    Well, for me it's back, after almost two weeks of perfect TivoHD enjoyment. Came home today to a frozen TivoHD. <sigh>

    I am experiencing freezes as well with a TiVoHD with FIOS.

    After a reboot, they freeze in the same place. Interesting, it does not happen during the commercial. I am wondering if it has something to do with Dolby Digital.

    Once it crashes the TiVo and rebooting. Any ideas?

    Thanks,

    Rich

    Recent freezes,

    can happen while watching live tv

    switching to "now playing" or main screen reveals animations are working as normal

    switching back to live tv gives a normal picture ( though several times it quicky froze again)

    I have not been able to isolate a live recording freeze as of yet to check the exact point on the recording

    in general any switch of screens or pressing forward reverse buttons alleviates the issue atleast temporarily

    Is everyone with the problem using HDMI? Does anyone have the problem with component inputs?

    It has never frozen while I was watching a recording -- I never watch live tv.

    Since emptying the deleted folder to below 50 items (tivo with extender) I have had only 1 freeze and that was during a cable provider problem. May only be mine but the folder empty seems to really improve things.

    The strange thing is my other Tivo never freezes and I just ignore it - they are exactly identical using the same cable cards etc.
