Really interesting. I can't see of hand how this could happen.

The only possibility is that the input bitstream somehow gets corrupted
sometimes and because of that UVD fails to decode the field in question. But
that would affect normal playback as well.

Anyway, please open up a new bug report for this. Clearly a separate issue.
