Map Fullscreen on Texture to the whole screen

Here's a question. 

I understand the difference in playing the video on a texture and sending it to a fullscreen activity, but I have a situation where I would like to use the textured option, but map/force the four quardrants of the texture to the four corners of the screen, rather than dynamically calculate the vertices of the tracking image.

I have an idea about where/what to edit in VideoPlaybackRenderer.java, but would appreciate any advice on doing this, if soemone knows exactly where to edit ... ??

Thanks...
