AS2. Youtube Video On Flash Website Suddenly Stopped Working.

Hi,

I had youtube videos running perfectly well on my website until suddenly they quit working.
All the videos quit. I had another website which had nothing to do with this one running independently
and just to double check when i checked that website, i found all the videos there also have stopped loading from youtube's site.

I think youtube changed something in their protocol ?

Im using.....

Holder_mc.loadMovie("http://www.youtube.com/v/ASO_zypdnsQ");

Suddenly they all quit loading. I tried on different systems etc. The whole jing bang.

Can someone guide me what code i should use ? Im in a fix and need to get this working immediately.

Thanks
