Video Rendering behind opengl window (how to make the opengl window transparent)



I tried posting in a solved thread, got no answer.
I’m rendering a video in Blackberry, but the video is being rendered behind the opengl window.

How (in cocos2d-x version 2.0.3) can i make opengl window transparent in other to show the video (for those who have the example, the video window example shows how to, but i cant see where in cocos2d-x i should make it);
