University Lectures Online

I have always though that my university should videotape lectures so I wouldn't have to attend, and it would really help when it is time to revise for a test because you could just watch the lecturers with the relevant talks, but Massachusetts Institute of Technology has already put all their Guest Speaker Lectures Online. You can watch lectures on all kinds subjects, like How Cancer Begins or Democratizing Innovation (essentially talks about user created content).

The videos all stream very well, but they are encoded in ram format, so you are going to need a copy of Real Player or better yet Real Alternative, because it won't crash your system like Real Player does.
