Try the program Itube. I had it, and it worked, but the quality seemed to be shoddy. My sister used it though and the quality was identical to that of the youtube versions, so try it out yourself.
I don't have the site anymore. I just googled it. I think the code name may be Itube... Now that I think about it, the icon on my desktop said Ares Tube or something like that. It's all about digging through google. That's how I find EVERYTHING.
