Huh? There's new university lecture videos being added to Youtube all the time, so I don't know why you'd say everything there is old. Besides, for many (most?) subjects it doesn't matter if the videos are old or not. Something like, eg Linear Algebra, just doesn't change that much.

All of that said, one other option you might check out is videolectures.net[1]. There's some pretty good stuff there.
