Videos On Line Travesti Do You Know Of A Site That I Can Convert On Line Videos From Sites Like You Tube Or Yahoo! Videos To 3gp?

Do you know of a site that I can convert on line videos from sites like You Tube or Yahoo! Videos to 3gp? - videos on line travesti

I want a website that can only store the address or the URL of the site and convert the video to me. I would like Video to 3GP (cell phones) to convert, because I want to see my videos on my Nokia.
Or, if a Web site that would be the videos have already been implemented, it's easier for me. Please help me.
