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.
Are there any "side channels" that host university lecture videos and course materials for less fortunate students in 3rd world countries? The ones on MIT courseware or Youtube are old.
I mean something along the lines of academic torrents etc...
