Graeme Segal is the speaker of the Felix Klein Lectures 2011 [4] organized by the Hausdorff Center for Mathematics. Upon popular demand, the Max Planck Institute for Mathematics is producing video recordings [5] of each of his six lectures on "Three roles of quantum field theory".
We are offering the lectures in three different formats (flv [6], mp4 [7] and webm [8]), so there is a chance that you can watch the videos on your favorite operating system with your favorite browser. Since these are the first videos on our new website everything is still a bit experimental...
