I found a what appears to be a great price on DVD-R discs. Only thing is, will they work with iDVD and the Pioneer drive.
Here's the place I found the cheap DVD blanks:

BTW: I have the Pioneer drive (104) which I installed into my G4 466, and iDVD is compatable! I have burned movies and played them back in my dvd player. Drive $380, iDVD "upgrade" $19.99.
