Вы должны изменить размер большого пальца после того, как он будет загружен в приложение. Функция SetupThumb может быть изменена:

/** setup video thumb */ 
    public function SetupThumb($cat:int, $id:int):void 
    { 
     _id = $id; 
     _cat = $cat; 
     _thumb.contentLoaderInfo.addEventListener(Event.COMPLETE, resizeThumb); 
     _thumb.load(new URLRequest(XMLData.GetThumbLink($cat, $id))); 

     SetThumbOut(); 
    } 

    private function resizeThumb(e:Event):void { 
     _thumb.content.width=100; // You may specify any other size 
     //_thumb.content.heigth=100; 
     _thumb.content.scaleY=_thumb.content.scaleX; // Resize proportionaly 
    }
