I have a new MacBook Pro
If you are still within your 15 day return period. Call Apple they will sent out iDVD at no charge. (There are no realistic substitutes.)
Nicely explain that you may return the computer without iDVD. That usually does the trick. You MUST speak to a senior advisor to get a free copy. The first tier people cannot do it.

800-692-7753
Is this the only way?
Yes, there are programs that will put a movie on a DVD. I have tried most of the other substitutes including Toast, Burn, and others. None of them come anywhere near the ease-of-use and power of iDVD. IDVD is specifically designed to work with iMovie.
I'd like to go the free route...
IDVD is a wonderful piece of software and well worth the low cost of $42.
