How to stop video at scene change?

I have a video player in a multimedia presentation I am building in Flash, which is almost complete and just having one problem. When I change the page (scene change), I can still hear the audio form the video. The Video is still playing, how can I stop this?

I was thinking if I added a stop function to all the buttons that link to different pages, but I don’t know how to refer to the FLVPlayer. Somethink like

Bio_btn.addEventListener(MouseEvent.CLICK, StopVideo);

function StopVideo ???{
???();
isPlaying = true;
}

but how do I write that function? and refer to the FLVPLayer??? Or is there a more fundamental way of dealing with this issue?

Help Appreciated
