Here's a link I got from Adobe, they've got lots of videos from NAB2008 for those who missed it; great job by Adobe on capturing all this for everyone:

There's 39 pages of 6 videos each! - the first 3 pages, about 18 videos, from NAB 2008... that Adobe has put together for everyone to watch, at no cost, and no email/optin needed. Wonderful job, Adobe!

p.s. Karl Millers' presentation on the new Adobe Media Player is a must-watch for all of us in video - it's the lower right video on the homepage.
