HR20-100 stock. I have two problems that I never had before; one makes the DVR really unuseable. I have rebooted several times. 1. I now have many recentrecordings that say they have recorded the full program, but when I push Play, the play bar shows a full bar of orange but then it jumps to end and shows me the Delete/Don't Delete option that you get at the end of the viewing a recording. So I can't watch any of these recordings. 2. A little harder to describe: Wake up in the morning. The DVR is recording a channel and the DVR is "tuned" to another channel that I was watching when I turned it off the night before. The problem is that the channel I was watching is black and no sound. If I tune to another channel I get the same thing: no picture and no sound. I then tune to a OTA channel and I get picture and sound. Tune back to a DTV channel and still nothing. If I tune to the recording channel I get picture and sound. I can fix this by going to Settings > Sat & Antenna > View Signal Strength -- get warning about this will stop my recording > Yes, Interrupt. As soon as I do that the PIG, which was black, now starts showing the channel. It's pretty clear to me that the UI layer thinks everything is OK, but the lower-layers hijacked a tuner overnight. This only happens early in the morning. I know I have an old DVR, but so far it has served me well. Now I really dislike this box. I'm going to talk my friends who use other companies. Should I try to get DTV to replace my DVR (I know I'll have to sign up for two-year contract, but I don't want to pay for a new DVR)?
