Good thing that wasn't a real bet, or you'd be out $1!
If I leave the GPU speed at stock, taht's when it'll freeze. I was running
overnight on liveTV, and wouldn't you know it ten minutes after I check on
it in the morning it locked up. That was at 300 MHz, so I figured I'd bump
it all the way down to 200 MHz (hey it worked for you) and let it go through
the day and see where we're at.
If I leave the VRAM (nee virtual arm... :) ) at stock speed, I don't get
freezes, but I get green video corruption after just a few minutes. I
turned that down from 650 to 500 MHz, and at least that part of the problem
has not happened again.

Not a bad test at all! Not one I can pass yet, unfortunately. Being
pragmatic, running for eight hours or so continously is probably good
enough. (I rarely watch more than an hour at any one sitting.)
