Jeff's advice is correct. I have the same hardware and this will get
720p working beautifully. However, on FC5 with the same hardware, I
can't get 1080i playing with XVideo. I am curious how things work out
for you.
When we were exploring it before, nothing seemed to resolve the
problem. I lost interest when it was proposed I build X.org and the
video player for debugging purposes to isolate the problem. I
understand why there's a need for that, but I don't see any easy way
to do that within the package management system. And building,
installing, removing and replacing X again isn't on my top ten list.
