Which version of Windows are you using? I test my program in two computers 
with windows xp and windows xp media center and gl/gl2 works (displays 
video).

Well, in linux I have 3D acceleration disabled, so when I choose gl or gl2 
it's extremely slow but it works, even resize works. 
But I don't know what would happen with 3D activated.

Now the problem is that I've never compiled mplayer in windows, but I'll try 
tonight.
