ATI Radeon and DVD Playback: overlay problems??

[Frederic Paugam]

I have allmost successfull results for vob files with a

radeon ddr 32
AMD athlon 1,4
dvd reader LG
XFree 86 4.0.3
Redhat 7.1

When i'm not in full screen, it's ok.

But full screen is slow and the video output is a little jerky.

Is my graphic card too little?
