    Not sure what you were seeing is the same issue others are having. Pixelation in my case is much more frequesnt than you were seeing.

    If the drive had trouble keeping up with the data streams then there is a problem with the drive. A 5400 RPM drive has no problem with several HD data streams. And these drives are 7200RPM drives. I had 5400rpm drives in one of my HR10-250 boxes. The performance was identical to the HR10-250 boxes I had with 7200 rpm drives.

    I find this tidbit interesting. When I called tivo about the macroblocking last week the CSR wanted to know when and where I bought the unit. He also indicated that while they didn't know definitively what was causing the problem, but that it might be the 'harddrive' on certain units. I didn't think much about this at the time because for a CSR the term 'harddrive' could mean just about anything but the remote control (disk, cpu, tivo, etc).

    I could easily imagine the following scenario for the defective units: the cable cards while decrypting/tuning digital channels occasionally cause a slight voltage {spike/dip} which somehow impacts writing the datastream to these sensitized disks.

    Is anyone with upgraded units still seeing the pixelation?

    Left the drive parameters as is out of the box. No acoustic management changes (which would derate a drive from its maximum speed in favor of quieter seeks). Some more hours of viewing will further tell if this fixed what I saw, but so far, so good.

    Jesus. Too bad that's inaccurate. "The issue is not universal but has been reported by a disproportionately large number of TiVo subscribers". Um, how many subscribers does TiVo have - something like 3 million - and how many people have reported it here? Unless this writer has secret inside access to TiVo's support call logs or his interpretation of "disproportionately large" is different than mine, I think that's a poor turn of phrase.

    He also mentions that Motorola cablecard users are immune, which isn't the case. No wonder so many issues get blown out of proportion. Idiot.

    I upgraded the hard drive in my unit yesterday and am still seeing the problem, even in Tivo units. I did enable acoustic management for the new drive.

    I think I figured out how to fix the issue!!!

    1. Put the unit in a box (don't forget the remote)
    2. Bring it out to the car
    3. Drive it back to where I bought it
    4. Get a refund

    I was giving it a chance, but on top of watching intermittent flashbacks of Tetris throughout watching shows (even when showing static shots with no movement) my unit decided to just reboot without warning yesterday. When I came home and turned on my TV, I saw 'Just a few minutes more' which meant my shows weren't being taped.

    NEVER had this kind of thing happen with my first TiVo which I've had for 7 years.

    What a joke this thing is. I give up. Goodbye TiVo!

    Well, there's no doubt that returns are going to drive Tivo to get a solution out sooner rather than later. If this was a simple fix we already would have seen it rolled out. I'm still surprised that they didn't run into this in testing.

    On the other hand my wife is totally falling for Tivo (I'm jealous) so at this point it doesn't look like ours is going back. I will report the issues to Tivo and if they don't get them resolved in the next month or so then I will expect them to work out some kind of refund, etc.

    not sure if anyone has the same issue as I do, but I get (really bad) pixelation on 2 channels, and those 2 channels only, on tuner 0. I've tried swapping the two cablecards, no difference. I checked the signal strength, and those 2 channels have lower numbers than others (low to mid 80s vs mid to upper 90s on others). rebooting didn't seem to help. maybe I should give it one more reboot. or do something to increase the signal strength. anyone have recommendations on improving signal strength?

    You forgot:

    5. $86 in hole for cable card install.

    Number 5 is what is keeping from returning the unit at the moment. I don't like these near hundred dollar learning experiences.

    actually I do not think the article blew it out of proportion. There is a distinct issue here and Tivo has acknowledged it and is working on a patch to go further than the Aug. 1st patch. TiVo knows it is working with initial launch impression of the product so I expct they are burning overtime on it and want to get it out ASAP.

    So some details are wrong like Motorolla cards not having issues but the overall impression of a new hardware release having some issues is accurate. My faith is still in TiVo getting it worked out and standing behind their products to continue their line of great products with another stellar product. Right now that is a faith thing though and article is just pointing out the current reality

    There are plenty of things wrong with that article, but that's not one of them. It fits with my definition of disproportionate. There's a proportion of TiVo subscribers who have HD, a lot of those complain of are reporting problems. That's disportionate.

    I haven't heard of many TiVo HD subscribers who said they didn't have problems. There are a lot, a disproportionate amount who are complaining of the problem. Usually when anyone claims a problem is widespread, a lot of people pop up to say they don't have the problem. I haven't seen that. You don't need access to logs to get a sense of this sort of thing.

    They did, if you want to call the release of the S3 a test. I have pixelation on my S3 which I talked to TiVo about several times. In my case the problem got better over time and for me the unit is now acceptable, but not perfect. They did offer to send me a new unit but otherwise had no interest in working with me to solve the problem.

    I think that if they had taken the pixelation problems more seriously with the S3; really gotten down to the core of the problem, or problems, then maybe they could have avoided this repeat performance.

    Look at the bright side, I doubt the next HD unit that TiVo releases will have this problem. Not after this B sample test confirmed the results from the A sample test.

    I'm writing to a Cnet editor who reviewed the TiVo HD about all of this. Took some pics to e-mail him also. Maybe if this issue gets exposure, you guys will get some help, but I've still given up.

    I was literally thisclose to picking up a Tivo HD after work after making the decision to treat myself and making the leap into HD, but after perusing these forums, have to admit that I'm running scared. Should I sit back and wait? Swallow the bullet and pick up a Series 3 for the extra dough? Suffer through with my Series 2 in SD?

    I've only been with Tivo for ten months and I can't believe I ever watched TV without it (never did the cable provided DVR thing and don't wanna, to be honest), but all this talk of pixelation, etc. is really souring my mood...

    I would wait until the clear up the pixelation issue, unless you are sure you can get an m-card instead of 2 single cable cards. If you can get a multi coard cable card from your cable company I would go ahead seems like the mcard people are not having the same issue.

    Will do just that...anyone had any experience (or can point me in the right direction) to dealing with Time Warner Cable in Los Angeles? Thanks.

    Getting M-cards is seriously hit or miss right now. Most CSRs and installers don't know what they are, and even if they try to specify that you get an M-card on the install order it's possible that your installer will only get the S-cards.

    Actually had a show with so much macroblocking from last night that the recording eventually failed.

    Just curious...are these problems at all prevalent in the Series 3 $600 unit? Slow menus, pixelation, etc.?
