I have read that unless you have a G4 that came with a SuperDrive iDVD wont work with it. Is the fact that you are replacing the current CD/DVD drive and making the new SuperDrive the master the reason that you can now use iDVD? Is there any way to modify the carrier to put two drives in instead of a zip drive? I have a G4 that was out in Nov of 2001, don't ask me the name Sawtooth, Gb ethernet ... I figure even if you can modify the carrier for the drives you would have to remove the bottom faceplate so the media carrier could move out which would make a mess of the looks of the computer. Any thoughts? Eric Phillips
