Video portfolio site help

I have a Flash based website which features videos (flvPlayback instances) that slide in and out as a user presses either a next or previous button. Everythings works except I need all videos to stop when the next or previous buttons are pressed so that videos do not play in the background. I am open to using one flvPlayback with an XML playlist as long as the next and previous buttons still allow the background information(text) to slide in and out with each corresponding video.
