I've seen this happen where the problem was the broadcast stream. I got
an episode of Terminator: TSCC, but Prison Break (which airs right after
T:TSCC on Fox) didn't record and gave a 0-byte file. When I watched
T:TSCC, the station was flipping between their digital feed and their
analog feed, the captions were completely broken (in both the digital
and the analog-converted-to-digital-and-upscaled portions), and at
several places, the video completely disappeared (though audio remained).

stream and the fact that a friend who also records OTA saw the exact
same thing happen.
