[mythtv-users] Multiple tuners, multiple sources...

[Stelios Valavanis]

what about 2 different inputs going to 2 different audio sources. my tuner 
card uses the bttv audio module and i want to grab audio from there. but i 
also want to use the composite input for my vcr to plug into but obviously i 
can't grab audio from teh bttv audio module because the composite input 
carriies no audio. there doesn't seemt o be a way to configure each input to 
be paired with a particular audio input. there's jut one place for this 
representing the whole card.
