Mac Forums

First of all, one of my podcasts has an exclamation mark next to it and when I click on it, it says, "Poh's Kitchen does not seem to be a valid podcast URL. Please check that you have entered the correct URL and try again."
Why is it coming up with that?? And what does that even mean? I have never had problems with it before.

Second, I want to restore my iPod and it says that all my data will be erased... does this include everything in my iTunes library, or just my iPod?

Thanks for your help!
