Embedded clip won't unload

1

So i have a button that when clicked loads a site address (a youtube video) into a target movieclip. Anther button that should unload it doesn’t work. The video goes away, but you can still hear the sound, and it cause slowness and other loading problems.

;(;(;(;(;(;(

Here’s the code:

//// video player ////
vIdeoplayer.cLoseVideo.onRelease = function(){
trace (“Unload”);
vIdeoplayer._x = 815;
vIdeoplayer.targetie.unloadMovie();
}
//// video player ////

//// portaworld ////
videothumbs.captionie.portaworldPLay.onRelease = function(){
trace (“Playing”);
vIdeoplayer._x = 0;
vIdeoplayer.targetie.loadMovie (“http://www.youtube.com/v/GD21Rpf2pgM”, this);
}
//// portaworld ////

HELP!!! ME PLEASE!!!
