[MPlayer-users] NO-SPAM Xvmc? Nvidia or mplayer issue?

[Ivan Kalvachev]

Hi,

Bad Match error is know and already fixed bug. Use the cvs version.
It is caused by querying colorkey on surfaces that are not overlays.
(btw CVS version is always stable)

Unfortunately I hear bad things about 6600 video cards, I had an user that
got poor performance when running 1920x1088. With nvidia support help
he had tracked this problem to be hardware one. 
It seems that video card doesn't use overlay anymore and require video blitter,
and that there is not enough bandwidth or computational power to display 
and decode at same time.
Video blitter could explain why you had problems in 16bpp mode..


Wish You Luck
