When you buy a G5 does it come pre-installed with iDVD4? do you get the iLife 04 pack/box or is it all pre-installed? if it is, how do you restore iDVD if there is a system crash? Can you just install iDVD (or whatever) from the Disc?
I can't speak for new G5s, but my G4 came with a Restore DVD containing everything that came bundled with the system. I removed iDVD because I don't use it, and I can use that DVD to reinstall it if I want it back.
