dragDrop and start playing an *flv file

Hi all,
on my stage i got some mc’s:
videoContainer (this gonna be a hitarea, after the hit it must play a *flv file).
And a few mc’s which gonna be dragable.
For example ‘mc300’.

There’s a big difference between as2.0 and as3.0 and i wanna do it in as3.0

Right now i only got:


mc300.addEventListener(MouseEvent.MOUSE_DOWN, mouseDown);

function mouseDown(event:MouseEvent):void {
    mc300.startDrag();
}
mc300.addEventListener(MouseEvent.MOUSE_UP, mouseReleased);

function mouseReleased(event:MouseEvent):void {
    mc300.stopDrag();
    
}

But i am stocked! Someone could help me ?
Thanks in advance!
