[mythtv-users] Adding PVR-250 to already existing PVR-350 system

This sounds right.  I'm writing this from memory so may not be exactly
right, but first you add cards, and one should be /dev/video0 and the
other should be /dev/video1.    Then you create a video source (cable in
this case), then you map cards to sources (input connections?).  You
should make it something like:
[ MPEG2 /dev/video0 ] tuner0 -> cable
[ MPEG2 /dev/video0 ] composite1 -> none
...
[ MPEG2 /dev/video1 ] tuner0 -> cable

Maybe you don't have video sources for the other inputs (e.g., "none" as
shown above).  Dunno, I've never tried 'C'.  Try 'V' and see if you get
PIP.

Can't help you there, I never got auto loading of modules working (low
priority for me).  I just load them manually and they see both cards (I
have a PVR-350 and an Aver M179).

Make sure you can cat from /dev/video0 and video1 and play it back with
something like mplayer.  If you can do that you should be able to get it
working with MythTV with no prob.

HTH,
