There's a long-standing bug where if you have multiple channels that air 
the same content at the same time, but have different callsigns (i.e. 
HGTV and HGTVD), MythTV will record the episode multiple times.  Note 
that you should only change the callsigns to be equivalent if the 
content shown on the channels is "substantially identical" (which, IMHO, 
means completely identical).  So, changing both to HGTV or HGTVD would 
work around the bug.
