Hi, I don't think I have a USB stick, will a burnt DVD do?

I have a couple of movies that do it, not that many though.
My PC is wired in to the router, the xbox is wireless.
TVersity just seemed to work. I tried to get the windows extender to work which I did but it was very, very slow through the menus etc. Is there a step by step guide to getting it working via other methods then?
