Thanks Will,

I've managed to get X running over the PVR 350's TV Out using
ivtv-0.2.0-rc3e as you suggested.  The main problem now is the video
performance through mythvideo: it seems to play at maye 1/2 -> 2/3 of
the proper speed.  The files are xvids and they run fine when I'm
running mythvideo outputting to my monitor.

Is it normal for mythvideo performance to be so poor on the PVR 350's
TV Out and is there anything I can do to fix it?

thanks

Chris
