Not YouTube. Actual movies.

I'm not sure about movies, but I know you can watch TV shows at Hulu - Watch your favorites. Anytime. For free. (http://www.hulu.com/)

You can try here.

Before I found hulu and netflix, I used to use movie sister. I don't remember if it was a .com or .net or what but I found it googling, if you wanted to check it out I'm sure it would come up again there.
