I *think* I'm a little closer, but still somewhat struggling after playing
with this a few hours.  Is there a way to tell Myth to use specific audio
PIDs?  I can't seem to find a way to do this and worked through a number of
channels as you described above, but am not sure what else I can give myth
outside of the PIDs themselves.

I do get sound when playing back from mplayer something I cat from dvr0.
The catch is that if I play back I really have to specify -ac hwac3 for
mplayer.  This got me thinking that maybe Myth is not pasing AC3 out to my
spdif port.  I *do* have the MythTV option to pass AC3 turned on and I'm
using the .asoundrc from Jarod's site with mixed digital for ALSA.

Is anyone else sending AC3 from a DVB stream over SPDIF?  If so, what does
your .asoundrc look like?
