the guys who are getting proper fullscreen, can you test for me I'd appreciate it very much:

1.Set windows sound scheme to on
2.Go into COD, and map a function say like flaps etc to your keyboard, if you hear the ding or noise from windows sounds then its not working properly still.

OR

Take a video of the start up slash untill the main menu. I used fraps and it recorded the black and white stripe screen after the reticle splash screen. This also shows it isnt in proper fullscreen.

OR Video the game menus it just wont work for me

Below is what i get if i try the video the games start sequence. Fullscreen is not fixed. i think you will see this if you just try any of those things above.
