My HR20-100 has been fine for years, it even seems like the video and audio hardly ever get too far out of synch anymore. A couple weeks ago I started experiencing freezes during playback, not live viewing. Not the kind I am used to when the thunderstorm is 7 minutes west of me. The audio and video stop, then resume after a few seconds. If I hit any button on the remote the blue power light flashes once as it always does. But nothing happens. If I hit a remote button again the blue light does not flash. When the DVR unfreezes it does whatever remote command it got with that first click. It usually resumes right where it left off, but I have seen it skip ahead two minutes. I have done several red button reboots. I called and the tech said it is a know problem with "system slowness" and that engineering is working on it and someday a patch will be downloaded. They had me turn off "scrolling effects" but that had zero impact. There was another setting we checked, but it was already set as expected. Here are some specific cases: 1) Recently recorded episode of Big Bang Theory stopped 16 min into the show, then another short freeze 19 mins in and a long freeze 21 minutes in. 2) An older recording of $10 Dinners played all the way through with no problems. So did an older recording of Burn Notice and Iron Chef. 3) I get up in the AM and rewind CBS to catch the local and national news and weather and skip the commercials and other uninteresting bits, at 7:30 on morning I backed up to 5:30 and started watching and skipping, at 6:15 of the time on the recording I got a freeze, from then until 8:49 I got 23 freezes and three of those resulted in missing 2 minutes of programming. 4) I watched an 11/28 recording of ESPN NFL live on 11/29, I got 8 freezes in the first 15 minutes, then none for 8 minutes before I had to do something productive. I think this is pretty horrible performance. If it was system wide affecting all receivers or just HR20s there would be more hits in this forum or on Google. I suspect that I have a bad disk and not a software problem that is common to other users. Any suggestions? I am calling tech support again to see if I get the same story and I am going to ask for some relief on my bill since I am not getting the service as promised.
