ATI Cat 6.3 drivers and 6.3 based issues

I am wondering if anybody has been having issues with the 6.3, Omega 6.3 based, or the Zeropoint 6.3 based drivers. With this driver set I have been getting repeated GPU crashes while trying to test out Oblivion and Battle for Middle Earth II. I know the BFME II has stability issues to begin with but the errors I am getting seem to be VPU related and all error reports lend to this fact. If anybody is noticing issues like this with any of these games please post in the forums and lets see if we can work this out.

Test rig is:
650 Watt Aspire Power suppy
ASrock DualSATA2
AMD +4000
2GB PQI DDR400
NEC DVD-RW
Connect3D X800XT AGP
OCWorkbench Bios BETA3 (Reverted back from BETA5 to test if that was the issue.

I have also uninstalled and reinstalled sound and video drivers multiple times, cleaned the registry and all other sorts of nonsense.
