I have some downloaded stuff in my 'library' section. I ahve uploaded these fine onto my ipod. Now I want to delete them, but if I do, itunes no longer seems to recognise them. How do I delete them without losing the info please?

Also, I ahve downloaded an avi. (Movie) I cannot preview it, and I'm not sure how to go about putting it onto a dvd. I have Nero.

Thanks in advance folks!
