I have tried many different paid and free programs that allow you to download off youtube and others. The biggest problem I ran into is most of them have not worked half the time. If you know of a tool that works best feel free to let me know.

The best online tool, by far, is KeepVid. They allow you to enter the url for pretty much any online video site and allow you to download the .flv to your computer. You will the need a program to convert the .flv to another format or a .flv player. Both are easy to find via a simple google search.
