Is there any indication in the re-recorded file that it was re-recoded because 
the original was damaged?

I occassionally get recordings, I start to watch them and realized I had seen 
them before.  These may be re-recorded considerably later (the original new 
broadcast was damage, now I'm getting the repeat or syndication).

My only belief is that this is a re-record because the original was damaged. 
There may have been some minor glitches in the original, but it may still have 
been totally viewable.
