Radeon Drivers on Vista and above seem to have stopped supporting the IDirectDrawColorControl method of setting the overlay procamp.

There do appear to be some registry entries DALOvlYUVBrightness etc changing these seems to have no effect but they do apear to be modified by the tool Ati Tray Tools. 

What is the correct method for progamatically setting the overlay colour controls on recent Radeon cards, also can this be exposed via the Display SDK.
