I have a recurring recording problem with my new Comcast Pace DVR that's driving me crazy. Every once in a while the entire program won't record. When I start playing the recording, it will show that the recording is 60min long, but after playing a few minutes, it will suddenly show that the recording is 20min long, and it will stop after 20 minutes. It's not always 20min, but it frequently is. In other words, the DVR thinks it has recorded the whole program (and I think the red "record" light is always on for the whole hour), but it either only recorded 20 minutes or the recording gets corrupted somehow.
Any ideas for what could be wrong? Comcast replaced my Pace DVR with another one, but the problem cropped up again after a few days. It seems to accelerate -- at first only once a week or so, then a few times a day. It's almost worse than having no DVR, since it's the luck of the draw whether the program will complete or not.
Thanks for any help.
