When I first installed the os I noticed the problem with the driver it 
came with.  I checked and found where it suggested a proprietary driver 
and offered one other.  I chose the one that was recommended.  The bug 
showed itself with the driver that came with the install and the one I 
installed later.

I've had that card for about 2 years while the machine was running XP 
and didn't have this problem.  It only showed itself after I installed 
the latest Ubuntu and Kubuntu version as well as the other latest linux 
flavors I mentioned earlier.  Fedora 15 was the worst.  It would freeze 
the screen as soon as I started playing a video.  The others would let 
me watch at least for a few minutes before the screen froze.

Also if it's not a driver problem, what else could it be?
