It would be nice, although there would be some complications.  What 
do you do if you have two or more rules that match a given title?  
What if one rule matches more than one series and they just 
*happen* to have the same episode name at some point?  I'm not 
talking about "L and O" versus "L & O" here (in which case having 
the same subtitle is what we want to use for dupe-detection) but 
another power rule that cherry-picks from more than one series 
based on genre or credit information, in which case two episodes 
with different titles but the same subtitle are really not dupes...

I think the biggest issue might be performance.  Instead of just 
comparing a show against prior recordings of that show, Myth would 
have to do the regex search on your machine's entire recording 
history to build the list of prior recordings against which to 
check the new ones.  It may not be a big deal when mythfilldatabase 
runs, but it will hurt the GUI performance when you make schedule 
changes through the frontend.

All things considered, though, it's an interesting suggestion.
