Can't post multiple YouTube videos in an swf file

I’m making a little gallery of Youtube videos and I can’t seem to load more than one in one .swf file.

It seems that once one is loaded - another one can’t be played even if you completely remove the container clip from the stage.

I made a quick example of the problem here:;

Here’s the code I’m trying:

var videoURL:String = '';

function load_vid_test_1()
    _root.createEmptyMovieClip( 'video_1_holder', _root.getNextHighestDepth());
    _root.video_1_holder.createEmptyMovieClip( 'video_1', _root.getNextHighestDepth());

    _root.video_1_holder._y = 40;
    _root.video_1_holder._xscale = 50;
    _root.video_1_holder._yscale = 50;

function load_vid_test_2()
   _root.createEmptyMovieClip( 'video_2_holder', _root.getNextHighestDepth());
   _root.video_2_holder.createEmptyMovieClip( 'video_2', _root.getNextHighestDepth());

    _root.load_movie_and_stop( _root.video_2_holder.video_2, _root.videoURL, null, 'simple_load');
   _root.video_2_holder._y = 40;
   _root.video_2_holder._x = 250;
   _root.video_2_holder._xscale = 50;
   _root.video_2_holder._yscale = 50;
