This is different than Sedgewick's class but looks interesting. Locking the class isn't Coursera-wide. I actually took the Algs part II class, but can't access the videos anymore, while other classes that have been over for much longer (e.g. the Scala course) are still available. And some courses have video downloading disabled altogether for some reason, e.g. High-performance scientific computing.
