preloader for video as swf

Hi everybody

I'm trying to make a preloader for video embed as swf. But I noticed, that unfortunately, when I stop the swf in the first frame on the main timeline in swf and onEnterFrame function I'm trying when totalFrames==framesLoaded and play the next frame when these two variables are equal, this video is still playing when I go to the other slide. So I see slide but on the background I hear video on the other slide. It is possible to make preloader to video embed as swf? I know that I can embed in SL swf as 'flash', but I lose possibility changing volume using button in player.
