Sounds like my setup, except that cardid 1 is pcHDTV and 2-4 are PVR-250.

Do you actually care to receive NTSC over the air? I have done the same
thing but reception on the NTSC channels is poor here, so I only care
about the ATSC channels. I actually use cable to receive the local
non-digital broadcast channels and Directv to receive the "cable" channels.

Have you tried to increase the priority for the ATSC channels on the
HDTV card? Of course you should have at least two lineups, because the
PVR-250 isn't capable of HDTV so they shouldn't have those channels in
the database as being available to record from.

The program guide shouldn't be cluttering as it joins the channels based
on callsign(?). I actually have 3 lineups on DataDirect. One for
broadcast, one for cable, and one for Directv.
