    I get the occasional pixelization on mine. Also get the increasingly slower menus which require periodic reboots to temporarily fix.

    Software is 7.1a. 140- series 2.

    Analog cable. No cable box.

    I've had pixelation, audio drops, and slow menus since 7.1. I don't frequent these forums, so I was afraid it was about to die. Now it seems I'm not the only one.

    You are far from the only one. What model TiVo do you have and what is the current version of 7.1 running?

    My series 2 tivo is not running a cable box, has the 7.1b and still has the pixel artifact problem. It will distort the picture and drop sound, lasting about 3 secs and recover.
    This problem occurs about once every three or four hours of watching, so its not that big of a deal. I too find that I can backup and view the spot just fine.
    I do not watch that much 'live tv' so I dont know how it or if it shows up.
    My guess is that the problem lies in the interupt routines that keep the video hardware up to date with data, or less then ideal amounts of cache.
    Either way, the more I know about the internals of the box, I am pleasently suprised at the other wise great performance of it, on the simple hardware it has going for it.

    Just got off the phone with the Tivo Support folks. Was told development is well aware of the problems and is actively working on a solution. Fix will hopefully be pushed out in the next SW update. (Not sure exactly when)

    I was never told it's a hard-drive failure in my unit and in fact, the support person immediately transferred me to a supervisor when I explained the problem.

    For what it's worth, I've started doing a weekly reboot and that has kept me from having any problems. Although, I think that the more I record, the sooner I have to reboot. At least it seems this way. I tend to see the menus slow way down before any pixelation or dropouts appear. When I notice the slow down, it's time to reboot.

    Hang tight. Hopefully, we'll see a fix soon.

    OK, now I am getting really p'ed off with TiVo's attitude in some of there dept's.

    Suffice to say, through a "different channel" at TiVo they are also claiming they know nothing of any other pixelation issues other than the channel changing with cable boxes. They suggested my hardware was faulty even though I know for sure, and documented that to them in a detailed report, that it works fine with a software version prior to 7.1

    It is this attitude from TiVo that is frustrating me as I really like the whole concept. :mad: :mad: :(

    Also, even though it is out of warranty, this attitude just reinforces my opinion that even $1 is too much to pay for a replacement box because it is THEIR software that broke MY box.

    I suggest that anyone with these issues report them to Tech Support and request a REFUND of the service fees on that box from the date they started getting the problem. :mad:

    Some people here experienced reproducible pixelation/freeze problem while others experienced non-reproducible problems. The former will see the same problem on rewind/replay. I am thinking if the pixelation problem is caused by transient CPU load. i.e. the former happens during record and the latter happens during playback.

    I wish there is a way to find out if my TiVo is experiencing hardware problem or performance issue. Like current CPU load or number of disk errors, etc.

    Add me to the long list of Tivo sufferers...

    Bought a 540 series last August and everything worked perfect until about two months ago... then all hell broke loose. I get all kinds of pixelation and signal dropouts on the digital cable channels, but regular analog channels still work fine via the Tivo. Even now on some days everything is fine with no problems, but other times the problems are so bad you can't watch digital programming at all. About the same time the video problems developed I also started noticing a slowdown in remote functions and menus. I tried the "Clear Everything" option and things improved for a day or two, but the problems resurfaced. I have a Motorola DCT2000 cable box.

    At first I thought it was the hard drive going bad or a bad cable box, but now I see this is a major problem across the board.

    Tivo... your programmers need to work night and day to get things working correctly. I love your product when it works, but this is unacceptable... :mad:

    Soon, we'll be with our friends, stuttering, lurching past them or lagging behind, dropping whole words from our sentences, or stopping dead while they walk ahead. They'll look solemn and ask "Wow, man - got that update last night, huh?"

    So, is there ANY common denominator in our setups, besides 7.1x? It doesn't seem so, which means if it walks like a duck and quacks like a duck... this software is decidedly, um, "ducked".

    My setup is exactly the same as before 7.1. (I'm hooked to the router, but had these issues using a phone line as well.) NO problems whatsoever before 7.1.

    Sony SRV-3000 Series 2, lifetime, unhacked, Coax RF in
    No heat issues (not enclosed, internal temp 41°C, room never more than 67 - 68°F)
    7.1b, Service # 110-xxxx-xxxx-xxxx
    Wired, to a D-Link 624 router
    Scientific Atlanta Explorer 1850 cable box (digital), IR
    iODigital service (Cablevision, NY):

    RW or FF rarely helps. The break-ups remain and are seen on recordings & live TV, at any quality setting. Worse yet...

    Tivo To Go transfers choke on the artifacts. They are truncated at the point where the pixelation begins. However, my TTG transfers are reasonably fast. (~11 minutes to transfer a 30 min, basic quality show)

    This pixelation/dropout is on both digital and analog channels. PBS, The History Channel and History International are preferred victims.

    This doesn't happen after a channel change (!!?), but at random points of a show, even if channel's been the same for hours, recording or not, Tivo nearly full or nearly empty. All fine if TV is connected directly to cable box.

    A reboot will sometimes improve the menus and drop-outs for a day or so. Several times, though, the picture/audio broke up very soon after returning to live TV.

    The FF and RW are flukey - since 7.1, it's very hard not to overshoot the point I want, as the Tivo lunges forward or back many frames once you hit PLAY (on any remote). I only rarely have the hair-trigger "double button press" syndrome, though.

    I did have the ToDo List/Season Pass amnesia thing, but that seems ok now. The scrolling through the on-screen guide leapfrog phenomena still happens.

    I also have a ripping headache, I'm getting crabby and I even feel a stutter coming on. I'm not spell-checking, either. :p :)

    Read you later,
    Cary

    I've had similar problems since the upgrade. Coming from a PC perspective, I assumed the new software was too resource-intensive for the processor/memory... if it were a PC box I would have dropped in more ram to see if that fixed it. anyone know if it's possible to upgrade the ram in the tivo box?

    I see the same thing. The problem is definitely with DECODING for my TiVo. Anything recorded can always be played back flawlessly eventually, I just have to wait until the static and audio drop outs aren't occurring. And for me, it doesn't matter if I'm trying to play back something through this TiVo or transfer it to my other TiVo. Which makes sense because both are doing the same thing, that being DECODING the info from the HDD to either play or transfer it.

    I did find something interesting the night before last. For the first time in about a week my 240 TiVo was exhibiting the problem and it was bad. Totally unwatchable. So I decided to try to force an update to see if the software wouldn't update. However, the TiVo was already in the last stage of it's daily update. It was over 90% of the way done with it's last step so I waited it out and see if the software was being updated by chance. It was not, but after the update was complete, the static and audio drop outs were much less noticeable.

    Right. Sounds to me like maybe the processor can't keep up with the decoding of it's data while it's also doing something required, definitely during but also just after a program guide update.

    Thoughts?

    If you transfer the video to another TiVo and that TiVo has an issue decoding it then I would say you have either a DECODING problem on 2 TiVo's or the original TiVo has an ENCODING problem.
    I would say it is the later as when you transfer the incorrectly ENCODED show to another TiVo, the 2nd TiVo cannot DECODE it properly due to the poor ENCODING.
    If you had just a DECODING issue on your original TiVo then the shows ENCODED (recorded) to the HDD would be be fine and would DECODE fine on other TiVo's, as is my case.

    Does this make sense or did I assume incorrectly ?

    I'm not sure.... :)

    Let me try to clarify .... if my 240 in the bedroom is exhibiting the audio problems, I can neither play a program in the bedroom or transfer it to my 540 in the livingroom. My assumption is that when the 240 is decoding it's data, either to play it or transfer it, the output is "bad".

    So, the 540 in the livingroom isn't having a problem decoding what was transferred, beyond the fact that the data transferred contains the errors that the 240 encountered when decoding and then transferring to the 540. The 540 just encoded what it received from the 240....

    That any clearer or just more confusing?

    OK, now I know why you think it is DECODING. Your TiVo only DECODES when it plays back. All shows transfered to other boxes or to your PC are transferred ENCODED, they are not DECODED and then transfered. This is why you cannot play a show on your PC without a special media player plug-in to DECODE the file.

    Okay, after reading that several times, my head has stopped spinning... :)

    Are you saying that transferring a program does not involve the same decoding process that playing does? I would assume that in transferring a program, the first TiVo decodes the data then transfers it to the second TiVo which then encodes it to it's hard drive. That could be totally wrong. If in fact it just transfers raw data without the decoding/encoding of data then I would think you're right, I should be able to transfer one program to another without the audio problems following the program, regardless of how the first TiVo is acting at the time.

    I'm pretty sure the bad audio follows the program to the second TiVo, but I'll do a little testing when I can and verify that. If I'm right and the bad audio follows the program, then the audio drop outs should be in the exact same places on the second TiVo, regardless of how many times you play and replay them. Because those drop outs are encoded into the data on the second TiVo. Correct?

    Not sure, but like you and I, one would assume he has other more important things to do besides posting on threads.

    He also wouldn't post unless it was worth posting with important info

    I would LOVE to read first hand from someone at TiVo that they're aware of the problem and are working hard to address it...
