SylviaN, the link doesn't work, period, and the only way you could have got it to work was by messing about with the URL, you certainly didn't get directly to the YouTube video by clicking on it.

That is because the URL as supplied by Jed is faulty, it reads

http://www.youtube.com/v/4VmatGaZSxg

whereas it should read

http://www.youtube.com/watch?v=4VmatGaZSxg

using the latter URL gives (I hope) the correct link
