If you have the time for it, you could also try these:  
http://www.openculture.com/freeonlinecourses

Press Ctrl + F and type "Computer Science"

many of them might use nonfree code on their websites, but it's a tradeoff.  
(But be aware that streaming all those videos can consume a lot of  
bandwidth.)
