Active Movie Window - How to fix?

Hi - Windows Media Player 10 is installed on XP Pro SP2. All of a sudden,
when I play videos, I get a pop up that says Active Movie Window instead of
the video simply playing in WMP. Here's a screenshot:

Computer is virus, spyware, and adware free.

Question - How do I disable this Active Movie Window popup so that the video
plays in Windows Media Player 10?

Thanks

Joe

 

One site says "The problem is solved by reducing video hardware acceleration
(in the advanced display options -> troubleshoot) by 3 steps ("Disable all
DirectDraw and Direct3D accelerations, as well as all cursor..."

Another says that it's a side-effect of a particular version of XVid codec

I've already done a Google search.
