If you go to YouTube.com and cursor all the way down you'll find a spot to click on for the handbook. They have guidelines for uploading videos there. They don't really recommend any specific format, but mention that they can accept almost any format -- MPEG-2 and MPEG-3 are specifically mentioned as "preferred." Basically, I would stick to one of those.
