What is your video hardware? i915 and later use textured video and that was 
what I was talking about. I have also had this problem on an i855 but it is 
not reliable as you say, but on the i965 it _always_ crashed when the Xvideo 
extension was  utilized on driver version 1.7.2.

This is probably because the BIOS runs, resetting the hardware to a sane 
state.

This is actually a known bug, I'm not sure if it's related to this thread or 
not. Search fd.o bugzilla for I830WaitLpRing. I've had it before and it's 
gone away inexplicably.
