need help with multiple external video 2

hello. I found this code online which is perfect to deal with multiple video. the problem is i want to make each item drag-able including the flv playback but i cant since it was not MC. can anyone help me please.

mc_buttons.addEventListener(MouseEvent.CLICK, newVid);

function newVid(e:MouseEvent):void {
var newVidName:String = + “.mp4”;
myPlayBackComponent.source = newVidName;
