I've been chasing this error for a long time. Mainly it happens during the morning news shows-I would get the error almost every minute or so and have to re-select play. i think maybe I solved the why but not how. If I stopped the recording (I have passes for several morning shows) the error would go away, so it seems that there's something going wrong with recording/playback while recording. i changed the path to another hard drive I have to see if that changes anything but wont know until tomorrow. Anyone have issues like this?
Another thing that seems related is if I watch a recorded show (but not watch while it's being recorded) I sometimes get choppy playback and it will often playback a part that I just watched.
