I found a Godel, Escher, Bach class on MIT's OCW (http://ocw.mit.edu/OcwWeb/hs/geb/VideoLectures/index.htm ) but the video lectures are in streaming Real Media format. It'll be over my cold, rigor mortis locked body that I ever install RealOne on my computer again, so I was hoping someone could recommend a (preferably free) program to rip the .rm streams to a local file format.
