As your logs are telling you, you appear to have neither i)
accelerated Xv video support installed for your video driver nor ii)
Xv support compiled into your installation of MythTV. Fix this, and
you should be sorted. Not sure if the open source radeon driver
supports your card.

The fglrx driver should provide Xv support though, so check to make
sure it is installed correctly@

# xvinfo

You also appear to have a problem with your audio device, but get the
video output problem fixed first.
