FlvPlayBack and fullscreen

I am using Flvplayback for a video player, on the page I have a screen on 400 x 300, with a control bar, then to the right side is a menu with the available videos.

I am looking to a way that I can put in a fullscreen option.

I have tried opening a new page with a larger screen on it, but I cant get the first flash player to pass the location of the file that is been played to the full screen player.

I have also seen a flash player that has a full screen mode like a video player you would have on your computer.

Any ideas, hints, tutorials or code would be great
