Full Screen problem with loaded .SWF

I am making a video player that will be used every where on my site. The full screen button works fine on the FLV player I built, when it is embedded in html, but if I try and load it through another SWF file that is embeded in html nothing happens at all. I tried sending a reference to the stage to the loaded swf and that didnt work. I also tried calling the fullscreen function from the container SWF and it didn’t work. It seem that any time there is more than one SWF the fullscreen function deosnt work. Is there some weird security thing I am missing? I have tried everything and looked every where and still cant find the problem.
