If your channel lineups are different on the two systems then the  
incoming shows will appear to have been recorded on different  
channels. This is purely cosmetic, you'll still be able to watch the  
shows.

There's also the possibility that an incoming show has the same  
source/channel/starttime as an existing one. This won't work in the  
DB and probably not in the filesystem so you'd have to check before  
moving the files into your recordings directory. Something like this  
is good enough to test for collisions:

	(ls /dir/of/old/shows; ls /myth/tv/dir) | sort | uniq -d

duplicates will pop up. Should you see any rename the incoming file  
to something else and use the svn version of contrib/ 
myth.rebuilddatabase.pl to import the show.
