Many schools these days have webcasts and podcasts of lectures. Many professors readily embrace new technology. Approach the professor and ask him or her if s/he feels comfortable recording and broadcasting the material. If your prof is cool, s/he will probably want to post the lectures (provided you assure your prof that people will still attend class!!!)

I went to UC Berkeley, and we did have webcasts of some courses. I never skipped lecture in lieu of class. That’s a big mistake people make: they rely on the webcast to show them everything. But there’s no true substitute for going to lecture and asking questions. Instead, the webcasts were great because if I missed any points in lecture, I could go back ot the video and fill in my notes. also FABULOUS for reviewing material before the exam.
