Loadmovie mess

Hello I have a 900x600 px web page runnig in Fullscreen, and I am loading external swfs to it with loadmovie(); the problem is when I loade the imagemovie the movie runs very slow. How can I fix this ? Is there any way to stop the main timeline to pause while the new swf played. Because I load all page on top of my main movie.

also even I loaded new swfs the buttons’ hover areas under the loaded one ( on the main swf) stay interaactive.

This is Urgent.
