ITunesU freezes iPad

Running iTunesU 1.3 on my iPad 2 iOS 6.1. I was attempting to download the lecture 4 video for the Stanford "CS193P Winter 2013" course. All of the following froze my iPad 30ish seconds after the trigger requiring a reboot:

Click on the iCloud icon, then stop it while still 'Preparing to Download' (tried this three times)

Click on the iCloud icon, then stop after the download has begun

Start the down load, the switch networks (screen went black for this one, still froze)
