Hmm...  apparently I spoke too soon.  Here's whats happen.

After a reboot, without mythbackend starting, I can cat both tuners
and play the mpg streams with mplayer just fine.  It seems as if both
tuners are on the same channel though, which may or may not be a
problem.

I start mythbackend.  One tuner works, the other is snowy.  I kill
mythbackend, cat both files, and only one works.

I'm not sure what this could be at all.
