DVD capabilities upgrade on Macbook?

[marketmac]

I have a MacBook with non-superdrive capabilities. I have now made a short movie that I would like to burn to DVD, but I have no Superdrive! Is there a way to upgrade now or use an external DVD burner to burn from iMovie? My operating system is Leopard and, of course, I have iMovie 08.

You can use an external, or use iDisk to use another computers drive.
