Thank you very much ! Thought it worked with the adress !

Yo you want to learn how to embed youtube vids? Step one: open up your post, go advanced.... Once you are there you see a youtube button in the top right. It will look like this (or similar) {youtube}{/youtube} once you push it. Step two is go to youtube, find your video, again in the top right is an embed url... it looks like this... <object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/1Hl7rwpdOPE&hl=en&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/1Hl7rwpdOPE&hl=en&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>

Put that embed link in between {youtube}{/youtube}
