"I went through the online tutorial to do this manually some time ago, and
chickened out because of the complexity."

Ah, but that's exactly why I created Buttonizer: it does *all* the complicated
installation stuff, so you don't have to.

You just click on a button's name in the list, and then click the "->" button to
copy it between your "My Buttons" folder (supplied with the program) and
iDVD.

Don't wait for somebody else to try it--give it a go yourself! It's so simple
that I
promise you'll be able to install the three new buttons that come with
Buttonizer inside of two minutes after launching the program. (Creating your
own will take a little longer.)
