[mythtv-users] Missing obvious PVR-350 config issue?

[Jason Lindquist]

After a few months' downtime, I have my MythTV box up and running again.
Oddly, both live TV and recordings via the PVR-350 card are faulty.
There is no video (only a black screen) and one channel of audio is
silent.  The card *is* functional, as I can dd /dev/video0 to a file
and get an MPEG-2 which plays back just fine (picture and stereo audio)
in QuickTime Player (on another host running OS X.)  Unfortunately,
mythbackend seems to be losing the picture and one channel of audio.

Am I missing something dumb and obvious?
