Forumlar / Cotonti / Support / youtube , metacafe video's in forum

Just had look in Admin>>Others>>BBcode, can't seem to find youtube code there.
Got our site running on Genesis 0.0.3, while upgradig i replaced all files in the package.

Both versions below won't work for me:
[youtube]HI1S6bKrh6w[/youtube]
[youtube=HI1S6bKrh6w]

What should be other files to look, already checked the system functions.php and the core>forums files but can't find any of that stuff there to.

Can't find those bbcodes in markitup plugin also.
