Comment 55 for bug 275285

I have a quite similar problem: video freezes for about 1 second randomly but it keeps going on.
This happens using dragon and mplayer and it doesn't seem to be related to the kind of file.
I've also noticed that the mouse pointer becomes active every 5-6 seconds.

More info:
- xserver-xorg-video-intel (2:2.4.1-1ubuntu10)
- xorg-server 2:1.5.2-2ubuntu3
- kernel 2.6.27-9.19-generic

My Xorg.0.log is full of lines like these:
