[mythtv-users] Video source config help

[Kevin Kuphal]

I have a problem I hope someone with some more insight can help me with.

I have a working MythTV box using a bttv/btaudio card configured as:

Video: /dev/video0
Audio: /dev/dsp1

This works to watch Television video with sound off the coaxial connection

I want to be able to record from my S-video input on the card to dub tapes,
etc.  It appears to the operating system as

Video: /dev/video0
Audio: /dev/dsp2

Specifically also with the mixer line set to Line3.  

I'd like to set this system up so that I can switch from TV to Composite and
then record from that input.  Is this possible using MythTV?  Do I need to
set up another capture card definition?  Or is this something that needs to
be modified inside MythTV itself to define an audio source for each input on
a tuner?
