How to download youtube videos free?

I buy music often but I like to watch videos on youtube too.(Please don't beat on me) Because my connection is so slow (mobile broadband) trying to watch youtube videos is pointless where I live. So if I could download the video on a better (friends) connection to watch when I get home that would be fantastic.

I asked on Y/A and got 10 different answers. I wanted to ask the experts before trying any of the suggestions!

Thank you,

P.S. I tried the 'activity window' method and all I get when I try to open the file is..'file is not a video file.'

Do a Google search and you will find many programs that will enable you to do it.

TubeTV works well. What browser(s) are you using? Both Firefox and Safari have native or add-on download 'helpers' where, I understand, you simply click a button and the YouTube video being watched downloads to your computer.

Thanks for your answers.

I am using Safari.
