сам разабрался

start_video.addEventListener(Event.ENTER_FRAME, handler);
start_video.addEventListener(MouseEvent.CLICK, start_video_onClick);
start_video.buttonMode = true;
var start_video_ToPlay:Boolean = true;
function start_video_onClick(evt:MouseEvent):void {
    if (start_video_ToPlay) {
		start_video.removeEventListener(Event.ENTER_FRAME, handler);
		start_video.gotoAndPlay("_down"); 		}
		else {
		start_video.addEventListener(Event.ENTER_FRAME, handler);
		start_video.gotoAndStop("_up");  		}
		start_video_ToPlay = !start_video_ToPlay;
}
function handler(event:Event):void {
	if (start_video.hitTestPoint(root.mouseX, root.mouseY, true)) {
		if (start_video.currentFrame <= 9) start_video.nextFrame();
	} else {
		start_video.prevFrame();
	}
}
