Thanks for your reply re Ticket #3125: my tests suggest that at present
I get no benefit from XvMC. I've disabled it and things work. Maybe
it's because my card doesn't implement it fully:- the manual for nv
build 9631 says "GeForce4 MX, GeForce FX and newer products support
both XvMC's "IDCT" and "motion-compensation" levels of acceleration.
GeForce4 Ti products only support the motion-compensation level" - so I
get no cosine transform support.
But there were other problems with enabling XvMC that affected xine and
mplayer too: all reported that they couldn't find the dynamic.so module
unless the *full* path to it was specified in /etc/X11/XvMCConfig. That
changes with each release, and I understand that this is not what is
HTH, John P
