I'm not able to record WOW using DIRECTX/OPENGL Window. When I press F12 or the Record button it hangs up my WOW for a few seconds but doesn't record. When I use Rectangle on screen I'm able to record the game with no problems. So I'm wondering what is going on when i choose directX/OpenGL option that is not allowing me from recording.
Specs

ATI Radeon HD 6970 2gb. I have the most current drivers installed.
