Does anybody have URLs for the videos? Clicking on the video link for a lecture asks you to install Silverlight.
It's actually not just a video, but a specially designed player that shows the lecture video and the slides in sync, along with a bunch of bookmarks so you can jump to specific slides.
Try it in Chrome. At least on the Mac, there's a dedicated but cut-down version, which does not require SilverLight. It's based on FlowPlayer and it also seems to work with Flash disabled.
Lecture 6 seems to be offline, unfortunately.
Video is displayed using Flash Flowplayer, you can extract mp4 from the source
for example first one is http://scs.hosted.panopto.com/Panopto/Podcast/Embed/257476ca...
