[mythtv] dual tv cards - modules.conf

I don't think there is any way to modprobe bttv
multiple times. The first time it comes across a bttv
in modules.conf I think it will detect both cards. If
they both get autodetected properly that shouldn't be a
problem. Otherwise you might have to make some changes
in bttv-cards.c for the cardnumber your tuner gets
detected as.

I have gotten both my cards to work with xawtv even
though the Pinnacle cards reception seems a lot worse
than the AverMedia. I haven't been able to get btaudio
to work for either card yet (don't know if they support
it) so I enabled my onboard sound and have two
soundcards set up, and it seems like everything is
working except for when I try to use both cards in Myth.

When running mythfrontend I get the following:

Probed: /dev/video0 - Television
Probed: /dev/video0 - Composite1
Probed: /dev/video0 - S-Video
Probed: /dev/video1 - Television
Probed: /dev/video1 - Composite1
Probed: /dev/video1 - S-Video
Probed: /dev/video1 - Television
Probed: /dev/video1 - Composite1
Probed: /dev/video1 - S-Video

This doesn't seem right, or is it? And then when I try
to use the Picture in Picture I end up not being able
to issue any keyboard commands to Myth. Are they being
directed to the PiP that I for some reason can't see?

Anyway it doesn't seem like anyone else is using two
cards - except for Isaac.

Let me know if you get any further - I'm pretty much
stuck, or if anyone has suggestions on how to
