WPMU Dev Videos not showing

WP3.0 and BP 1.2.5.2 install. The 10 introductory videos were available a few weeks ago but they don't show up on either on my sites now. I can embed videos on posts and pages so why these aren't showing up is a mystery wrapped in an enigma for me.

Any ideas?

Thanks for looking.
