Grazie per avermi risposto

var loader:Loader = new Loader();
loader.load(new URLRequest("Galleriahome.swf"))
loader.contentLoaderInfo.addEventListener(Event.CO MPLETE, onLoaded, false, 0, true)
function onLoaded(evt:Event):void{
addChild(loader)
evt.target.removeEventListener(Event.COMPLETE, onLoaded)
loader.x = 10;
loader.y = 200;
}
per il secondo video utilizzo lo steso per modificando

var loader1:Loader = new Loader();
loader1.load(new URLRequest("dep.swf.swf"));
loader1.contentLoaderInfo.addEventListener(Event.C OMPLETE, onLoaded, false, 0, true)
function onLoaded(evt:Event):void{
addChild(loader)
evt.target.removeEventListener(Event.COMPLETE, onLoaded)
loader1.x = 500;
loader1.y = 200;
}
