You are better off using the content in iTunes U, but you need to use Google and search for it, it doesn't come up otherwise. The course you are looking for is in Spring 2008 and you can listen to it here https://itunes.apple.com/us/itunes-u/philosophy-189-spring-2008/id461120614?mt=10
Division one is also there under https://itunes.apple.com/us/itunes-u/philosophy-185-fall-2007-heidegger/id461120554?mt=10
Apparently it does come out in search on iTunes U but it's not in the Philosophy category so you need to hunt for it manually, by going to the UC Berkeley front page and then going into Spring 2008 on the right. http://itunes.berkeley.edu
