Hello, everyone. For the last few months my TivoHD (single drive, upgraded to 1TB) has been experiencing issues playing back recorded content (I haven't noticed this on live - but then again, I never watch live). Sometimes the picture will simply pixelate a lot, and sometimes it will pause for a few seconds, or even jump ahead by 10-20 seconds (for example, it might jump straight from one Jeopardy question to the answer for the next). In my area all channels are digital (Wide Open West), and this occurs on both SD and HD broadcasts. So where this gets a little odd is the consistency or lack thereof. Some programs will stutter or skip a half dozen times in a half hour. Some programs playback perfectly, even from the same channel. However, it's pretty certain that if we watch a couple hours of TV, we'll see several glitches an evening. I've run the Kickstart 54 and 57 tests and everything passed. I haven't had any problems with booting up or using the Tivo, no spontaneous reboots, and I haven't heard any noise to indicate drive issues. My temperature is a bit high (49C), but just within tolerance. Signal strength is consistently above 95%, and SNR is 36dB. RS Corrected and Uncorrected are both 0. In other words, despite the issues I'm seeing everything seems to check out. Does anyone have any advice? I don't know whether my Tivo is dying, the hard drive in it is dying, or if my cable provider is sending (a lot of) bad data down the wire. I's lean towards the drive, except the tests don't back up that theory. Also, if it comes down to replacing the drive, is it possible to upgrade a TivoHD (non-XL) to 2TB these days, or are we still stuck with a 1.1TB limit?
