I have had a Comcast DVR since the beginning of the year. Whenever I try to record Poker After Dark, it records for 350 minutes or more instead of 60 minutes. Anyone else have any similar issues? Almost every night I DVR stuff on History and Science Channel without issue. Nothing else has had a problem, but Poker After Dark consistently messes up. Since I usually have my DVR in the 70% ranges, I can't afford to have it record 6 or more hours instead of one.

Comcast DVRs are junk, but I haven't had that particular problem. Have you called CS and gotten them to send a reset signal? I find that's necessary periodically.
