The University of North Carolina, Chapel Hill, in the USA has a series of over a hundred videos Information in Life at http://www.youtube.com/
view_play_list?p=19189F4C412A6E09 - although the North Carolina channel is on youtube it isn't subject to the normal length restrictions and many of the videos are of lectures or longish interviews. 1 hour lectures aren't always that enticing to watch, but there are some interesting speakers and interviewees in there e.g. Danah Boyd on social networking and Joanne Marshall on evidence based librarianship. I noticed this item in the IFLA Social Sciences Libraries newsletter by the way.
