If the shows have the exact same programid (and by that I mean /both/ 
shows), the subtitle and description can be completely different and 
Myth /knows/ that they're the same episode.  Myth will /never/ record 
the exact same episode /at two different times/ unless you disable 
duplicate checking.

If the shows air at the /exact same time/, however, it's not a duplicate 
matching thing.  It's a bug in Myth where two shows airing at the exact 
same time on 2 different channels (meaning 2 different callsigns) both 
get recorded.

Nope.  Data is irrelevant.  You can change the callsigns of the 2 
channels to be the same(assuming their content is "substantially 
identical"--which, IMHO, should mean exactly identical) and it will only 
record one copy.  Or, you can fix Myth.  There's probably even a ticket 
for it, but I don't feel like looking it up (as I'm hungry for dinner 
and it's midnight, now).
