How to use Color Controls with AMD Radeon 5450?

[tafreire]

I have a Radeon 5450 and an onboard AMD 760G. And I use Windows XP (yes, I like Windows XP interface).

I can use the "Color Controls" only with the onboard VGA 760G. With the Radeon 5450, the Color Controls have no effect (do nothing), even on Windows 7.

Only with the VMR9 "Rendering mode" I can use the color controls with the Radeon 5450, but the video quality in this mode is very poor.

I use the AMD video driver 12.3 for the onboard VGA 760G and the 12.8 for Radeon 5450.
