Как-то

var videos:Array = []; /* of Video */
var quantity:int = 30;
 
nsPlayer = new NetStream(nc);
 
for (var i:int=0; i<quantity; ++i) {
  var temp:Video = new Video(maxWidth, maxHeight);
      temp.x = 0;
      temp.y = maxHeight * i;
      temp.attachNetStream(nsPlayer);
      temp.addEventListener(MouseEvent.CLICK, switchNode);
  videos.push(temp);
  addChild(temp);
}
 
nsPlayer.play(flashVars.Str_name);

Дальше к видео можно обращаться так:

Video(videos[i]).x = 10;
Video(videos[i]).y = 10;
