Here are the archived justin.tv videos: http://www.justin.tv/startupschool. I believe I heard something about edited videos being available at some point as well (can anyone clarify that?).
I've heard from multiple sources that they will appear here: http://webcast.berkeley.edu/events.php. I don't know if that means Berkeley did their own recording, or if this will just be less compressed version of the same videos.
Thanks.
