Bizarre "grayscale" video - please help?

[gene.yue]

Okay, here's the problem. About 4 or 5 months ago (not sure exact time of start), SOME video I would play would not give correct color. Instead, the video would be in a "grayscale" going from a bright washed out white to a dark blue-ish almost black. Totally odd. SO. Here are some facts.

It is not a program problem. It happens whether I use WMP or Zoom player or BS Player.
It is not a codec problem. It happens on ALL codecs except....see the next point.
Both QT and RM files work fine. Nice pretty color with no issues.
It is not a file problem, as it happens with every file, whether downloaded, created myself, OR a web stream such as MSN Video.
It is NOT a monitor issue, I have tried another monitor.
Since its not just on one player, it can't be a plugin problem.

I have replaced the following with no fix:
WMP
DirectX
NVidia Video Card drivers
BS Player
EVERY Codec I could find


If I could figure out how to screen-cap WMP playing a file to show you what I mean by grayscale, I would. Any ideas on how to do that?

More importantly, any ideas AT ALL on what this could be? Before I reinstall Windows I want to hear some ideas, please! =)

Thank you in advance for any help.

ok well u didn't mention that u uninstalled all files of windows movie
maker. Also, try downloading a clip off the internet and see if that works.
cut off about half a second from the clip, that usually works when somethign
like that happens.
