Well, I didn't know anything about it but I guess now I know
enough to run a program through it. This is what I got once
I pressed V:

[New Thread 9226 (LWP 26799)]
VIDIOSYNC1: Interrupted system call
only read 2048 from 4096 bytes from '/dev/dsp'
read audio: Interrupted system call

After this point it doesn't matter what key I press. It
could look like there actually is something messed up with
the audio. When I ran setup I associated both cards with
'/dev/dsp' even though I have the cards hooked up to
different soundcards.

I guess this is the next thing I'll try if you think it's
necessary based on info above.

I tried to change the capture resolution in settings.txt and
that worked fine.
