If it's of any consolation, I'm sitting with the same problem with an
X300.  I couldn't manage to get any driver to give xv output, although
I never tried vidix/gatos(not sure if this supports my card even).

The 'radeon' driver in xorg worked with my 9700pro, but this is agp
and the machine I need HDTV playback in is pci-express.

I REALLY don't want to fork out more cash for an nvidia card, and it's
pretty much putting my HDTV on hold right now (I picked up an Air2PC
card also).
