I'm still unclear on what to do here.  The two channels (A and B) ARE 
labeled differently.  They have different channel numbers and I used 
different channel icons too.  If I edit the call sign of channel B to be 
different, then it won't record at all, because MythTV records by call 
sign, which will no longer match the PSIP call sign value from the 
broadcaster.  I think there needs to be a way to just tell MythTV to 
record "this channel" and it does.
