Consistant BUG with some ATI Hardware & P-Pro 2

I've had issues with ATI GPUs on two seprate systems with CS2 (P-Pro
2)installed. One HP Pavilion AMD64 X2 4200 with onboard ati grfx, again on a
custom system with Gigabyte GA-M51GM-S2G MoBo, AMD64 X2 6400, Saphire ATI
HD2600xt 512mb pci express.

On the HP sytem I had consistant crashes when opening the title maker. Never
figured out the issue.

On the Custom System, again with the title maker causing crashes, plus the DV
out stream would suffer from drop out to no signal periodicly (every 20 - 30
secs). Through trouble shooting found if I set playback settings off GPU
assisted and standard, only using compatible mode, both issues would go away.
New Drivers and or elimination of catalyst control center did not help. Using
the onboard Nvidia grfx cleared everthing up, no issues.

I have one Intel system employing an ATI card and it does fine.
