I have made it so that youtube videos now use the new style from the current version of the youtube site.

Note that you should NOT use the OLD way of importing youtube videos instead use the NEW insert video button that lets you enter the COMPLETE URL. It also supports mutiple websites!

Example:
PHP Code:
[video=youtube;5lBeai-NCnM]http://www.youtube.com/watch?v=5lBeai-NCnM[/video]
