[mythtv] Can't find matching decoder

[Keir Christian Lauritzen]

I'm using mythtv-0.11 and I recorded the O'reilly factor for several
nights.  If I try to watch one I get

Couldn't find a matching decoder for:
/mnt/store//2032_20030904040000_20030904050000.nuv
Changing from None to WatchingPreRecorded
>> Player timeout
Changing from WatchingPreRecorded to None
Changing from None to None

now I have never had this problem with any other show but this one and
recordings of other shows before and after have been fine.

What would be causing this?
