Radeon x300-x800, Xvideo and DRI?

As a user I can tell you how it works for me.

My setup is an X800 XT AGP in an Athlon XP system and I've been using 
DRI for some months now.

I have no idea as to the stability of PCI-E, dial-monitors, or dual-link.

XVideo works fine as long as you don't use OSD on top of the video 
(causes corruption around the OSD).

DRI works fine in many cases as long as your expectations are too high ( 
no Doom 3 & Quake 4 doesn't work :)
Also you have to use the Xorg CVS for the best result.
