When I double-click on a video (avi or mpg, DivX or Xvid), instead of WMP opening I get nothing. But if I look in task manager, the wmplayer process is running at 100%. I can kill it, and the problem will repeat the next time I try to open a video. WMVs open just fine though. If I open WMP first, then open the file, no problem. I had the latest version of the DivX and Xvid codecs but removed them both in troubleshooting to no effect. I have reinstalled WMP and DirectX to no effect as well. I have also disabled video acceleration in WMP to no effect.
