@unggnu: What do you mean by "Overlay for video output isn't used anymore in current Hardy"?

I guess your video is not played via xv, but via X11/shm. Please try mplayer -vo xv file.avi . Video rendering should go trough xv. All other video output methods consume either too much CPU (X11/shm) or could interference with other applications (gl output breaks games, compiz).

Although I agree with you, that actually, using the intel driver, video playback is smooth with x11 output compared to xv with compiz enabled.
