YouTube Video Playback Issue

Hi I Have This Block Of Code (ActionScript 2.0) On The End Of My Movie On A Keyframe:

[codebox]
movieurl = "http://www.youtube.c...CEdSPHzA&hd=1"; // YOUTUBE VIDEO LINK
createEmptyMovieClip("video_mc", 100000); // CREATE MOVIE LAYER
video_mc.loadMovie(movieurl); // LOAD URL
video_mc._x = 350; // X POS
video_mc._y = 250; // Y POS
video_mc._xscale = 100; // SCALE
video_mc._yscale = 100; // SCALE
stop(); // STOP ANIMATION[/codebox]

How Can I Destroy The Movie Completely, BTW I Have Also Tried A Few Codes Like:

video_mc.unloadMovie();

Which Does Infact Hide The Video From The Stage But The Sound From The Video Continues Playing Back :S

Does This Mean That The Video Layer Has Not Completely Been Destroyed, Or Has It Been Cached :S
I Dunno Lol I'm Quite New To Flash And ActionScript. I Think It May Have Just Been Temporarily Been Removed

But Any Ideas Would Be Greatly Appreciated,
Thanks In Advance,
