Actually, a broken seek table won't necessarily result in an inability 
to seek, it could also manifest as slow seeks or blockiness when seeking 
or other issues.  So, if you see any kind of issue when doing anything 
other than just playing the recording from start to end, you probably 
want to try to rebuild the seektable on that video (since you know you 
may have some corrupt seektables).

They'll be deleted.  If the data that links them to the recording got 
corrupted, then they've already been deleted (mythbackend cleans up that 
table once per day and gets rid of any records that don't correspond to 
existing recordings (where existence is determined by database metadata, 
not file/file system info).
