I believe the wiki has more information on the Chromakey OSD fix. With
nvidia 4xxx and 5xxx series there is a Chromakey hack that will give you a
color OSD and fix the stutering issue. However, the feature that is
exploited in the hack isn't available on on 6xxx and newer cards. I have it
working on a fx5200 card. If you really care you could get a different video
card that supports that hack.
