My HVR-1600 is sorta working on Mythtbuntu 9.10.  I tried the tuner and
wasn't happy with the audio issues and didn't want to deal with building
the driver myself.  I am wondering if you may have any ideas for me?  I
have a working PVR-150 in the box and would like to set up the HVR-1600 to
record S-video input.  The video recording works, but I don't know how to
grab the audio that goes with it?  Any suggestions?  If you have any
questions about my setup details, I'd be happy to provide answers.
