x

hey all,
is there a recommended way to upgrade your xserver? i dont know how to..

i got the following output message from xine-check

[ hint ] Your X server doesn't support YV12 overlays.
That means xine will have to to color space transformation and scaling
in software, which is quite CPU intensive. Maybe upgrading your
X server will help here.
If you have an ATI card, you'll find accelerated X servers on

[ hint ] Your X server doesn't have any XVideo support...
XVideo is an X server extension introduced by XFree86 4.x. This
extension provides access to hardware accelerated color space
conversion and scaling, which gives a great performance boost.
If you have a fast (>1GHz) machine, you may be able to watch all
kinds of video, anyway. You will waste lots of CPU cycles, though...

think this is what is causing the jittery playback.
