"Copyright Disclaimer Under Section 107 of the Copyright Act 1976, allowance is made for "fair use" for purposes such as criticism, comment, news reporting, teaching, scholarship, and research. Fair use is a use permitted by copyright statute that might otherwise be infringing. Non-profit, educational or personal use tips the balance in favor of fair use." Does that mean you can use anything aslong as your not making money? I seen that on lots of YouTube Videos

No it doesn't. Whether you are making money of it or not (commercial application) is one of the factors considered, but not the only one. So there are plenty of non-commercial applications that are still illegal. As for usage of copyrighted material on Youtube, this is generally "safe" since it's going to be Google that is ultimately responsible for copyright violations on their site, and well, suing Google isn't all that much fun for minor violations.
