No, just one recording rule (any time, any channel).  The listings data 
match what was previously recorded.  They are complete with 
season/episode number, episode sub title, and description.  They are not 
generic listings.  I am stumped as to why this happens.

It is not that big of a deal, since it is easy enough to delete the 
re-recordings.  It just seems like something not working as it should 
somewhere.
