I'm trying to download iTunes University: Stanford iOS 7 course videos. I need them for a long train ride and flight I have to take so I can work on my development while I'm traveling. The thing is, only some of the videos download and the others stop harshly at specific even MB amounts (2.0 MB, 8.0 MB) with error 9006. I've tried: Removing partial downloads, quitting iTunes, recreating my library, deleting the "partial" listing from My iTunes U so I can restart the process, subscribing/unsubscribing to the collection. No matter what, specific videos from the collection will not download. I downloaded 2, 3, 6, 9, 11 and 12 but the others just keep crashing before I can download them. I try downloading them one at a time. Some times they get to 8.0 MB, some times they get as high as 50% but they keep failing no matter what. My internet connection is rock solid and there are no drops when the crash happens.
