For the nVidia and Gatos drivers I use (and I assume the driver
Ben uses) the 'normal' Hue is a 0% or 100% and 50% is whacky.
This seems bassakwards to me. It may be that the SIS driver sets
the Xv hue the right/wrong way (or the wrong/right way).
Try starting video, press F five times to get to the Hue setting
then right arrow to 50% and let us know if this fixes it or not.
Isaac made the Xv picture settings a TV Settings->Playback option
now so you can update and simply turn off the Xv settings but I'd
first like to find out if the SIS hue values are reversed.
