2.57b VideoTexture Bug

OK, so I found a cool tutorial on www.tutorialsforblender3d.com and downloaded the file, it works fine if in the 3D view port all’s you see is what the camera sees if you render it, but if you zoom out it goes buggy and the view gets what the inactive camera is seeing gets drawn under what the active camera sees. It works fine when I run the .blend with blenderplayer.exe so it’s just a dev bug.
If you open the attached file and run it while you can see the camera clipping lines (I think that’s what their called) you can see some spinning Suzanne heads behind the game view port and the TV plane is incorrectly textured.
but if you zoom in so you can’t see the lines, it works fine and all you see is the one camera view port and the TV plane is correctly textured.
