How to view iTunes U without itunes?
Here's an alternative which worked for me without using iTunes:


Get course URL, for example:

https://itunes.apple.com/us/course/this-text-doesnt-matter/id775395339

Use a feed extractor like feedflipper. This eventually gives you the raw xml file: 

https://p1-u.itunes.apple.com/WebObjects/LZStudent.woa/ra/feed/COFFWM26TD

The file is served as text/rss so may not display nicely in the browser.

Open with an RSS reader OR
Download as *.txt file, reopen in firefox and use DownThemAll or alternative OR
Copy the entire XML file and use a link scraper like the one built into JDownloader.
