[mythtv-users] No sound with DVD playback

[Bennett Leve]

I am using mplayer to play DVDs via mythtv.  If I plug headphones into 
my soundcard out, I can hear the sound from the DVD.  For mythtv though 
I am using the sound out on my PVR-350 which works great.

Shouldn't I be able to take a mini-stereo plug from my sound out and put 
it on the line-in on the PVR-350?  When I do this, I have no sound.  
Maybe there is something that needs to be configured, but not sure what.
