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?
