You sure it isn't 'Y'? C switches between inputs, Y switches between cards.

That is how it works. This has come up in the past, but this hasn't
been a particular itch with any of the developers. I started to look
into it at one time, but after staring at the code for a while decided
that I don't watch enough live tv to worry about it (I was actually
looking at adding this functionality for my wife). If a patch was
written that was up to the coding standards, there is a good chance it
would be accepted.

Two lineups are fine. Just setup the one Directv lineup and assign it
to both capture cards. This is what I do.

Increase the priority level of the HDTV card in the card setup (or
increase the HDTV channel priority in the channel setup).

I am not sure where the mixed NTSC and ATSC support is on the HD-3000.
I know there has been work done on this recently. I don't think it is
0.17, but it may be in CVS. I haven't really paid attention as I use
two PVR-250 for my Directv receivers because I wanted both to record the
same way (MPEG2). With the HD-3000 video in you will need to record in
RTJPEG or MPEG4 (unless this has changed). Plus this will take more CPU.
