I have a season pass for "Cheers" on WGN and it's worked fine for the last 4 mos that I've been using this R15-100. In the last 7 days though I've had an odd issue where the recording is cut off by ~ 7 minutes. While replaying the recording the beginning is there, but at around the 4 minute mark the recording seems to have had 7 minutes cropped out of it. There's a little stutter at that point then the remaining plays to the end without issue. The 3 times it has happened it's always the first Cheers recording that day (2 episodes record back to back). Could this be a HD issue (I have over 80% free), a guide data issue, or ????
