Apple made iDVD to work only with Apple internal OEM hardware. Some external drive company made a patch so their hardware would work with iDVD but Apple's lawyers changed that. You should be able to use Apple's DVD studio pro just fine from what I understand since it is a program that you can buy to work on any computer, unlike iDVD which comes bundled to work only with Apple's Superdrive equiped computers. -Preston >iDVD 2.0 works just fine. Ran 2.1 updater and then 2.1 at launch says >"iDVD could not be opened because the required hardware could not be >found". Anybody know the work around or does 2.1 require G4 or what? >
