The ICON right below the Italics button in the toolbar when posting is the Youtube button.
Just click it and then put the video ID of the Youtube video between the brackets.
Here's an example for the video at http://www.youtube.com/watch?v=xz9E_zoYdlc
xz9E_zoYdlc is the Video ID
The link gets posted like this: {youtube=425,350}xz9E_zoYdlc{/youtube} ( but replace the '{' with '[' )
