Vista - Vista RC1 (Build 5600) and poor WMV playback

I purchased The Benchwarmers with Movielink in XP and had backed up the video
to an external harddrive. A few months later, I installed Vista RC1 from the
ground up (which was fast!). I restored that backed up video, and now it
plays horrifically. It has color issues, and it displays itself almost 3
times in different colors as well. I also tried playing some WMV-HD files
from Microsoft's site, and they proceeded to do the same thing!

Is Vista WMV-HD just not working correctly, yet?
