It's most likely due to the use of an "overlay." I'm not sure of the technicalities of it, but it would explain why the settings for the video card have no effect. Imagine that the video playback, or rather the rending is outside of the scope of the desktop. I've seen some cards have two sets of settings, one for the desktop, and one for the overlay.
Here is a picture of the Nvidia's older drivers allowing adjustment of the overlay settings:
Unfortunately I can't quickly find a picture of the newer Nvidia Control panel. What you're probably going to want to look for is adjusting the settings of OpenGL rendering since all of XBMC (As far as I understand) is rendered in OpenGL.
