Xv picture controls on GeForce 6200TC
In a nutshell, is it possible to adjust color saturation and hue in the Xv video texture adaptor on a 6200 card?
The long version: I just purchased a PCI-E GeForce6200TC based card that I was planning to use for watching video. I'm using the 8178 drivers. Functionally, everything works fine. However, the color saturation of the Xv video overlay is set so high that it's unwatchable. All of my older graphics cards have Xv picture controls for saturation, hue, brightness, and contrast. These controls are missing on the 6200 card. I'm connected to a plasma TV through the DVI port. Because it's an RGB connection, the plasma has no way of adjusting color saturation and hue.
Is this just a missing driver feature, or is the 6200 hardware not capable of providing these controls? If the 6200 card can't do it, is there some other PCI-express-based card that can?
