Luckily my machine is powerful enough withou XvMC, so I seldom use it. HDTV on my machine uses to be around 20%-25%, but now takes 30%-35% in 0.17. Abit high, but far from being a problem.
Yes, many people report xvmc problems in this sort of config. (I have the 5200.) However, not everybody gets them. You need to break into the houses of developers working on the xvmc/video playback and switch their hardware to something like your config...
One reason I suspect xvmc has not had this sort of priority is the difficulty of
debugging stuff like that, the intermittent nature of problems, and the fact that
other things become harder with xvmc so many people decide they would rather just
get enough processor to run without it. And the fact that there are always tons
of other things to do. You can search the dev mailing list for xvmc discussions.
I think the unichrome folks have xvmc working better. When I have tried unichrome
however I have had problems trying to do HDTV in xvideo, let alone xvmc. But I
didn't try too hard, since it's cheaper to just get other cards than to pound on
a card that's not working.
With XvMC, video quality do look better (mainly colours look more natural for me) , but I think it's possible for me to tune my machine to display vibrant colours without XvMC.. I for one love PiP and can't live without it.. :)
Guess the #1 reason why XvMC has problems is Nvidia distributes their drivers in binaries? It seems that to get XvMC working, audio will break, and after fixing audio, XvMC will break.. :)
