How can I delete iTunes U from my iPod classic?

I have an iPod classic that runs software version 1.3

I can listen to Itunes U episodes I've downloaded by searching by genre. However, I still cannot figure out how to delete them. I've searched a lot on the internet and there seems no option. Any thoughts? I dont want to wipe my ipod clean.

Does this information not help?

Alas, it does not solve the problem. I have the same issue this guy does. It just doesn't show up anywhere at all when I connect my ipod to my compuer.
