I believe Isaac was saying that MythTV defines three things in mythtvsetup:

Capture Card
Video Source
Mappings between the above two

You have your four cards already defined (NTSC, ATSC, etc.)  You need to 
create two lineups under your single datadirect account which you can do 
on their website.  One for NTSC channels and one for ATSC channels.  You 
then need to create two MythTV video sources, each one using the same 
datadirect account but make one the NTSC lineup you created and one the 
ATSC lineup.  Then finally, set up the mappings so that each of your 
NTSC cards uses the NTSC lineup and your ATSC card uses the ATSC lineup.

As Isaac said, if this is in place, MythTV will understand that 
overlapping callsigns are to be combined in the guide and you will see 
only one listing.  If you have your tuner card priorities set right 
(ATSC higher than NTSC), it will choose the appropriate card as needed 
when scheduling.

I would probably suggest dumping your lineup information and starting 
over with the above.
