Can't burn iMovie to dvd on new macbook pro??

I just got a new Macbook Pro in December and cannot figure out how to burn my imovies over on to DVD. It apparently doesn't come with iDVD which is a ripoff, therefore leaving no way for me to burn a DVD of the imovies? I looked at Toast, but I am really not interested in paying $80 for something that should have came with the computer (since it comes with all other laptop computers via some sort of program like Windows DVD creator). Someone PLEASE HELP, how can I get my imovie on to a DVD?
