Tivo resets itself

I have a Tivo Series3 (v 11.0m-01-2-658) with a dual tuner cable card and also connected via coax cable through a Cisco tuning adapter to the cable modem. Sometimes, when I watch a recorded show, (the McLaughlin Show to be precise; no other show causes this so far), the Tivo unit resets itself. Something in the recording is causing this because if I try to play the show again, it resets at the same point in the playback. It has happened often enough that now I try to skip the first seconds of the show. But today, it occurred in the middle of the show rather than at the beginning, like in the past.



I thought perhaps it could be because of bad sectors on the hard drive, but why does it only happen for that show, recorded at different occassions over the past months.
