    My first foray into Amazon VOD on my Premiere was to rent 'Morning Glory' in HD. I was surprised to find a few dozen instances of weird mpeg pixelation. They ranged from just a few pixelated blocks to a couple of instances of half the picture inverted/pixelated/shifted for as long as 2-3 seconds. There were what looked like minor split-second frame skips too. The problems were uniform throughout the viewing.

    The whole movie appeared to be fully downloaded before I started viewing. I'm not sure whether the problem was Amazon's, or something amiss with the Premiere, but it was somewhat disappointing that I couldn't watch a $5 VOD without having mpeg glitches strewn throughout it.

    Anyone else experience such a problem? Are problems with Amazon VOD on the Premiere common? If so, I'll avoid it in the future.

    Contact Amazon to get a credit. This is not the norm. I rarely rent movies on Amazon, but I do rent a bunch of TV shows at 1080i and 1080P24 resolutions to watch on my Premieres. Typically they will playback without any issues, although I have seen on rare occassion a glitch or two like you mentioned.

    It's probably Amazon's fault. I've downloaded a bunch of HD tv shows and some had pixelation issues -- even when I re-downloaded them.

    I've definitely seen in on amazon videos I have watched, but never enough to really bother me much. I do wish they weren't protected. I'd love to download them to my computer and play through the affected scenes with mplayer to see if a different player shows the same problem. If tivo is claiming a service update will fix it, then it is probably a tivo problem, not an amazon problem.

    It always seems once an issue is resolved, another crops up worse then the last...

    You'd think these folks would adapt to their environment, writing code that does as intended without opening awhole new canno worms

    Makes you wonder why we pay a monthly fee for crappy service?

    Far as the video quality from Amazon, it's been fairly good with some pixelation once in awhile...

    They have stopped the letterbox format which I was really not happy with during that period

    I've had the same problem with a couple of HD videos from Amazon. The last one I purchased kept breaking up so much that I couldn't keep watching and turned it off.

    I rewound the video to the areas where the pixelations occurred and noticed the image breaks up in same places every time so either it's a problem with the way the videos download to the Premiere HD or a problem with the Amazon source video itself. Not sure since I haven't re-downloaded the videos to see if it occurs again in the same spots.

    Very frustrating.

    Yes, I've been seeing this on almost every HD video I purchase from Amazon. It's very frustrating. I rented "Exporting Raymond" last week and it frequently had horrible pixelation problems. It was almost unbearable to watch by the end. I contacted Amazon about it and they gave me a credit.

    I thought maybe it had something to do with playing the file while it was still downloading, so two days I ago I rented "Enchanted" and waited until it had completely downloaded before watching it. It still had some pixellation moments (though fewer). The image even froze once while the audio kept going. I pulled up the same moment the next day and the exact same problem was still there.

    I appreciate that Amazon has been considerate, but I'd prefer to not have these problems at all.

    I suspect the problem is that the DOWNLOAD is still really just a 'live'-ish stream that is being recorded. So any interruptions in the data-stream are not corrected. Most of the videos I buy on Amazon download and playback fine, but close to half have a least one noticeable glitch.

    I've watched two HD rentals on Amazon Instant on my Premiere and Premiere Elite and both had some level of pixelation. Is anyone else still experiencing these issues?

    Since downloading from Amazon there have been dropouts on 90% of the content

    Amazon refunded my money for the most recent video downloaded. I'm hoping the next service update resolves the issue.

    We just watched Pirates of Carribean in HD and had no problems, just waited about 20 minutes before starting and it was fine.

    Folks, this may not be a news flash, but....

    I have 3 Tivos. 2 Tivo HDs, and 1 Tivo Premiere Elite

    I use the Amazon service to download HD movies on all 3.

    I never, ever, get pixelation on the Tivo HDs.

    I always, always get pixelation on the Tivo Premiere Elite.

    The Elite otherwise is performing very well, but Amazon HD downloads are absolutely horrible.

    All 3 units are on the same, physical, network segment, in the same home.

    All 3 otherwise have no video issues at this time.

    Though I can't explain why, this seems patently clear that it's an issue with the Premiere, and not Amazon. The only thing I have not done to troubleshoot this is to download the same movie to both the Elite and one of the HDs, as I'm not willing to throw good money after bad.

    This problem occurred as recently as last night. The movie Larry Crowne.

    Interesting observation. My issues were on a base Premiere and on my Elite with two different movies. It does sound very suspicious that its an issue with the way the Premiere platform is interpreting the downloaded file from Amazon. I never really had pixelation issues on my TiVo HD or Series 3.

    I've also experienced the issues on the Premiere. I would put it one of two categories. Caetgory 1: Sometimes it is totally AWFUL to the point where the episode is unwatchable and Amazon refunds my money (this happened with one of the Dr. Who Premieres). Category 2: 2 or 3 brief moments of brief pixelization in TV episodes.

    It's interesting, I don't remember having these issues on the Series3 either.

    I tweeted to @tivodesign about this. My problems were in your Category 2. Quite annoying but the two HD movies were still watchable. Amazon refunded my money for the movie I complained about. Maybe you can ask TiVo about it at CES! Hopefully all of these problems will go away once TiVO implements true streaming with Amazon.

    IMHO occasional brief pixelization or other glitches may be excusable in a streaming environment because that's more-or-less real-time. But the difference between streaming and downloading is that downloading isn't real-time, and thus should benefit from whatever handshaking and error detection and correction techniques are needed to ensure a perfect transfer. Computer file downloads are expected to be perfect these days, and movie downloads should be perfect too. I agree with bsmith1051 that they may be using the term "download" rather loosely.

    Let me say it again with more emphasis.

    The pixelation issues in my experience do not occur with my Tivo HDs. Matter of fact, I can't say I've ever seen any marked pixelation with either of them, and I've had them for quite a long time - pretty much since the release of the Tivo HD.

    The pixelation issues pretty much ALWAYS occur with my Premiere Elite. They range from relatively bad to incredibly bad. Like ridiculously bad. On the same, GB hardwired ethernet network. On the same network segment, same subnet, etc. Absolutely nothing different about their connection to Tivo/Amazon.

    Swapping locations (moving an HD to where the Elite is and putting the elite where the HD is) makes absolutely no difference. The issues follow the Elite.

    The Elite has zero pixelation issues with any live, streaming content, broadcast, etc. None. It also has no issues with content copied from one of the Tivo HDs - nor do they have issues with content copied from the Elite.

    Happens when there is zero other use on the entire network (in my home, obviously). I'm on FiOS.

    This to me totally discounts any possible explanation that it's due to "streaming signal loss", etc but is rather a symptom of something specific to the Elite. I'd love to hear a technical explanation as to how it's Amazon, or a "streaming issue" yet the Tivo HDs never experience this. I just don't see any possible alternative other than a Premiere Bug.
