compiz - Feb 2007 - Compiz slow when playing some videos?

Currently, compiz really deal well with most videos...

But some videos make compiz slow...
ex:
ftp://ftp.developpez.tv/tv/linux/2007/solutionslinux/Keynote2.ogg

Play it, try to move the window, you will have artefact...
Let the video play, launch firefox/konqueror, move the window, it will not be 
smooth :( With some others videos, no problem.

GeForce 7600 with nvidia drivers
Wobbly activated
detect refresh desactivated (doesn't work here)
sync to vblank enabled

Compiz launched with: /usr/bin/compiz --loose-binding --replace gconf

Maybe it's the decoding that uses a lot of resources and makes your
whole system slow. Which process is using most CPU? The X server or the
media player?

There shouldn't be any artifacts. Are you actually seeing drawing
artifacts or is it just slow?
