I talked to a representative at the Apple Store, and they told me that iDVD is only available if you got a SuperDrive PowerMac.
I knew they were wrong, so I talked to him a little more, and he said if you buy the Pioneer A-103 Drive, you must install iDVD. iDVD is available off ircle, or carracho. He had it on his powerbook, so he gave it to me there.
I was told that iDVD was STANDARD on all systems, but it is totally hidden if you do not have that drive.
I am sure there are hacks out to bring up iDVD with an external drive, or there is some way to do it.
