    8.3 has caused many of us to have problems that we did not have with 8.1. I keep expecting Tivo will fix this, but it must be a significant problem for it to be taking this long.

    Roll backs would be VERY useful.

    Apparently TiVo has begun pushing out a new software update for S3's, v9.1.L5. It's touting "Advanced WishList Features". More here.

    It will be interesting to hear if there are improvements for those experiencing macroblocking and other issues.

    Our S3 was buggy for about three weeks after v8.3.1 was released, but everything cleared up and has been fine ever since. Let's hope this takes care of everyone else! :up:

    According to this post the latest software upgrade, v9.1x, may have addressed the macroblocking issue that some S3 owners experienced with v8.3x.

    If you were having macroblocking (or other) issues with v8.3x, can you please post any changes you're seeing when you receive v9.1x? Thanks! :up:

    I am waiting as patiently as I can for the 9.1 update. If it fixes my macroblocking problems, I'll be sure to post. I really wish Tivo had stuck those of us who'd called to complain at the top of this rollout list, instead of randomly rolling out to people who don't have SA cablecards and the related issues.

    Thanks for keeping us updated. When the upgrade rollout begins for everyone you should be able to sign up for a priority download here:

    TiVo Priority Download web page. (Note: the page won't be active until the regular upgrade rollout begins.)

    Hang in there and thanks for keeping us posted! :up:

    Following up on this (can't figure out which 9.1 thread would be appropriate, and it seems like it makes the most sense here), 9.1 has helped, but has not fixed my pixellation problems. It seems like the macroblocking is less severe, and instead of knocking out sound and pixellating video for 2 seconds, it happens for half a second. Less frustrating, certainly, but it absolutely still happens.

    I'll call Tivo and let them know I'm still seeing this, but I imagine they think it's fixed.

    I've experienced some minor macroblocking issues and pretty consistent audio drops. I had about 4 incidents when playing back the latest episode of Dexter (each lasted about 3 seconds) but had a perfect playback of the latest Brotherhood (no macroblocking or audio dropouts). This is the same channel (Showtime), the same evening, back-to-back shows.

    Some channels are worse than others. FX, a non-HD channel, has the worst macroblocking and audio dropouts, sometimes even pauses in the video stream. I suspect TWC isn't playing nice with the cablecards. Why should they?

    the new software did not fix the problem. i'm tempted to say it made it BETTER, but now instead of "stuttering," it's doing some weird thing where it stops/mini-pixillates for a split second, then fast forwards to about 2 or 3 secs. ahead, and you miss what went on in between

    overall it's prob. better, but don't we deserve, didn'tw e expect a real, complete fix? (feel free to treat that question rhetorically)

    Its not made anything better, it's simply papering over the problem. What the Tivo is now apparently doing is taking the bad video segments and "fast forwarding" through them to make them appear shorter.

    this is no fix; the problem is still glaringly obvious

    Phew...I thought I was the only one seeing this new behavior. Its like the video and the audio get out of sync and the video speeds up to sync back up with the audio.

    I would agree, its not as annoying as before but it shouldn't happen at all...

    >>I would agree, its not as annoying as before but it shouldn't happen at all...<<

    overall not as annoying, but i watched an entire star trek episode, and then missed a climactic last line, as it "FF'd" throug 3-4 secs. of show. i knew the line by heart and it sucked that i didn't get to hear it

    tivo is putting through some software changes, as we've all noticed. don't know if they are trying to sneak in fixes for the pixillation prob. or not, but mine has gotten a LOT worse over the past 2 wks or so. many shows have this insane "fast forward" thing going on where you have 10 secs of show in 1-2 secs and you miss out big chunks and it happens more than ever! if they're experimenting w/new fixes, they haven't gotten it yet! others noticing similar?

    Update: I removed the external hard drive I had installed when the hack was first revealed, as I did not need it any more. Since then, almost all of my problems have disappeared. I get very infrequent (once or twice per recording) macroblocking, but it is less disruptive, as it does not flicker the whole screen and does not cause any audio drop-out.

    Thanks for the update...and very insteresting findings. The macroblocking you're seeing now would seem to be natural and expected from normal broadcast interruptions.

    Can you give us a few details?

    - Brand/size of eSATA drive, enclosure, cable, etc. that you were using.
    - Current TiVo software version.
    - Setup, i.e. cable, OTA, etc. and any modifications (splitters, amps).
    - Cable company/region.
    - Brand of cable cards (if known).

    Your info could help others track down their issues going forward.

    Thanks again! :up:

    eSata drive: I ripped the hard drive out of a Seagate Freeagent Pro 750Gb and put it into an Antec MX-1 enclosure to improve cooling. Cable is an SIIG Model CB-SA0111-S1.

    The Tivo was running on the previous versions (9.1, 9.2 I believe), as I removed the drive about a week before the latest update came in.

    TWC NYC Southern Manhattan cable with 2 cablecards, one splitter to one cable modem. This is the only device getting cable, and there are no unused splitter ports or wall ports.

    I think the cablecards are Hitachi (not sure where I remember this) - will the cablecard screen show this info?

    Next step: I will re-attach the drive and see if the 9.3 software made a difference. Also, another possible source of error is that the "official" eSata drive support came out, but I did not detach/re-attach the drive. Perhaps it didn't like that I had attached it using the original hack. Re-attaching now with 9.3 using the official functionality should disqualify those as sources of the macroblocking.

    For the record, the current level of macroblocking is not even worth mentioning, it is so minor. Totally acceptable. Furthermore, the nature of the behavior is different. Previously, the pixelation that charcterized the behavior would kick in about half-way down the screen, about halfway between the right edge and the center. Following about a second of white pixelation, the video would stutter or freeze and the audio would cut out for 3-5 seconds.

    The current macroblocking is a thin stripe of pixels along the bottom of the screen, usually 2-3 seconds, or a single large pixel near the lower-right corner that flashes once to as many as a dozen times over the course of 10-20 seconds. No stuttering, no audio loss, the content is perfectly viewable and the behavior is, as stated, barely worth mentioning.

    All good info, thanks! :up:

    FWIW, the latest software is v9.2.j. AFAIK you have to look at the cable cards themselves to find the brand.

    If you marry up your eSATA drive via P&P it will be very interesting to note if the macroblocking comes back. We see a little now and then, but it's never the same and usually happens during a very fast moving scene...just some pixels that freeze up for a split second here or there. Since v9.2.j was installed things are much better and we no longer experience the audio dropouts we had w/v9.1.

    Thanks again! :up:

    I've been having a consistent problem with a couple of HD channel where I get long strings of pixelated video & no sound. I get as much as 10 minutes in a 60 minute show.

    In spite of the fact that the signal level shown on the problem channels is near full-scale (without an amp in place), I decided to try the in-line amp solution. I found a VIEWSONIC VSA-601C on eBay, $15 shipped.

    I's now been in place for about 6 weeks & it definitely fixed the problem. I had just one 10 second eposide of the problem in the 6 weeks.
