    do you know when we will be able to get Tranfers on the Series 3 box?

    Not for nothing, but I spent over $850 for this box, and I would like it to talk to my other 2 Tivos. If I had known that many of the things I love about tivo will not be on this box, i would have thoguht twice about buying this.

    Also, is there going to be an update for the Tivocasts? I subscribe to Cnet and Heavy on my Tivo 2 boxes, but I noticed they were not on this box( And I noticed I stopped getting heavy and Cnet on my series 2 boxes as well)

    OK, then here's what I don't understand. I don't see where mpeg comes in on HD transmission. I know for example that D* decodes it's signals in mpeg 4 but my understanding is they are the only ones who do that.

    Again my knowledge of the actual transmission of HD signals is a bit limited but mpeg doesn't make sense to me.

    Do a search... there are posts all over the place stating that we'll be getting that (at least in a limited sense, with nothing solid on how limited it'll be) later in the year. If it's anything like the ETA for the "fall 06" update, it'll be spring of next year, but at least it's a timeframe.

    Check for that in the next couple of weeks. There's a few posts in this thread alone that state that it's being turned on likely next week, after the majority of S3 boxes should actually have the software to support it.

    HD broadcasts (ATSC) are mpeg-2 compressed.
    DVDs are mpeg-2 compressed
    Tivo Series 1 and 2 store video using mpeg-2 compression.
    Most of Directv and DISH channels use mpeg2 compression.

    Directv and DISH are starting to encode HD using mpeg-4 compression, as it uses less bandwidth.

    I do have this issue, but not on a regualr basis and normally at most one a half an hour. But I also had this issue sometimes before I got my S3. So I am not sure all of this is Tivo. I would say I get it more now, but I still had it a little bit before. So could it be a combination of a bad signal and how Tivo vs your cable box interacted with this signal?

    Mpeg is audio/video compression format:
    http://en.wikipedia.org/wiki/Mpeg
    Just like Jpeg is a still image compression format.

    Mpeg-2 and Mpeg-4 are just variations of the format. If the transmission is in mpeg-2 you need an mpeg-2-capable device to decode it. Same goes for mpeg-4.

    I don't know which of the 2 are used by the cable companies, but I think Tivo is said to support both.

    As with any standard, there are areas that are subject to interpretation. Maybe the cable companies (or whoever is the original content provider) have different take on those than Tivo. If that's the case I sure hope the mpeg decoder chip is upgradable via software updates to support such discrepancies.

    No, this is not supposed to be fixed in this release.

    Thank you for the very clear explanation. And FlippedBit I now have an understanding of how this can happen to some and not everyone.

    That's just a game of semantics - I'm not saying that the info doesn't exist, but if it isn't to be shared for our purposese it may as well not exist.

    Doesn't change my point that if it isn't publically documented, TivoPony (or anyone else) aren't going to just go and post about it in a forum or send a PM just becuase someone asked.

    That's because a week of guide data is cached. Once you get past a week it has to retireve the data from the drive which takes longer.

    This same things happens on my S2 sometimes. I don't see this as a bug or an issue.

    Has anyone else had an issue with the Tivocasts changing from dl once a week to hardly ever? Is trhis due to the casts themselves not renewing content?

    True. However, if Tivo receives many inquiries, you can hope they'll respond to customer demand unless there's a good reason not to.

    We have no idea why it hasn't been publicly documented. Maybe they left it off because it wasn't useful at the time (no HD capable Tivo), and they could quickly revise the documentation to add it. But we have no idea. The only way to possibly make any progress is to complain about it and hope Tivo listens.

    I can tell you in my experience the Moxi DVR I had previously to my S3 the pixelation and audio dropouts happened MUCH more with the Moxi. This was at the same time I had a regular digital receiver hooked up to an S2. The pixelation was bad on that also, although not as bad as on the Moxi, or maybe I just used the Moxi more, or maybe HD channels are just more susceptible to the problem. It could also be Charter has improved their service since I had Moxi. Guess my point here is unless you have the two boxes installed side by side with each other (off the same splitter with same cable length) it is almost impossible to tell if you are having a Tivo problem, cable (in general) problem, single channel problem (from cable), or a single channel problem (satellite signal or hard line to cable company) issue.

    Well that is interesting. I am thinking this problem is multi faceted and that all of the possibilities are happening to some extent. I never had the problem on my S2 in over 5 years. Another person reported seeing pixelation issues on FOX on their S3 and D* which implicates the broadcaster. If you are seeing it on the Moxi, S2, and S3 on various channels, then your issues may be unaddressable by TiVo. Those of us with issues only seen on the S3 can still conclude that our problem is addressable by TiVo.

    It would help if TiVo would let us know what they fixed. The comment that TiVo doesn't have release notes because "it is not a computer" is not acceptable. I can't think af a single valid justification for not having release notes. TiVo is just being lazy and not yet operating like a mature company. My MP3 player, Audiotron, print server, and router are no more "computers" than the S3, all have release notes for their firmware updates, and none of them cost $800. It is normal and expected for a device like the S3 to have release notes.

    I really appreciate the baby steps TiVo is taking since its inception... I had the DirecTV Series 2 for many years... then I got burned by the lousy DirecTV OS, which was terrible.... then I moved to Tampa, FL and tried Brighthouse's Cable DVRs... terrible, terrible... so I broke down and bought TWO Series 3 and a Series 2 with the hopes I could share my Series 2 material on the Series 3... the TiVO advertisements werent clear that you COULDNT do this.... anyway, we love the features on the Series 3 and I cant wait to get my latest update...

    One thing I did while trying to isolate this was to record the same content at the same time on both the Tivo and on the 8300. Only the Tivo indicated the issue. The signal levels to both boxes were the same and coming from same output levels from the whole house amp. 8300 indicated the signal level to be +7dbm with 36db snr. I reduced the signal level to the Tivo but didnt make a difference. Further reduced it... no difference. Had several calls with tivo who told me that it was likely due to the mpeg decoding issues already known about and fixed in 8.1. I only saw the issues on QAM sourced material. Never saw it on OTA or analog. Signature of the hiccup was always the same. Audio stops.... video continues.... time elapses.... (different timeperiod for SD and HD) audio then resumes and small burst of video pixelation aparrently as the streams resynced.

    I also added a 'high pass filter' to remove the 0-50Mhz return path sewer to see if it was interfereing with the QAM tuner.... no dice.

    Note that I dont attribute ALL pixelation issues to this... There are going to be transmission issues either local or network that can create similar things.

    :confused:

    The "OS" on the DirecTV Series 2 is the same "OS" as there is on the Series 3.

    Both TiVo.

    And other than now handling HD, it really hasn't changed much.

    Did you know that you can use the channel up and down buttons while in the guide to change by page? It will and always has taken a half second or so to populate the new page, but it still is faster than clicking down one at a time with the direction pad.

    That sounds like a pretty exhaustive diagnosis. Probably correct in your case. I think a lot of times this amount of research isn't done though and Tivo just gets the crap for it.

    Please note to others with the problem, I am not saying it doesn't happen, just trying to point out as SCSIRAID said it might not always be that. In my case I think i have had about 4 or 5 barely noticeable blips in the last 30 - 40 hours of programming I have watched. Not sure where my problem lies at all, with that little bit it hasn't bothered me.
