I upgraded my iMac G4 (flat panel, with SuperDrive) today. I prefer doing a full reinstall of any major OS upgrade rather than an upgrade install (because I am afraid there might be leftovers of the old OS that can trip me up later), and I did so.

The install procedure worked smoothly, but it did not install iDVD. An upgrader for iDVD is available for download from Apple’s website, but it requires the presence of iDVD 2.0, which can only be ordered from Apple for $19.95, not downloaded. And of course the iDVD 2.0 disc is not included in the disc set provided by Apple with the iMac G4 (at least, the one I got; I ordered my iMac the very day it was announced, perhaps people who got it with Mac OS X 10.1 were more lucky). Grrr…

I found a workaround, which is as follows: copy the disk image files iMac HD Disc 1.dmg, iMac HD Disc 2.dmgpart through iMac HD Disc 6.dmgpart onto your hard drive from the system restore CDs. then double-click on the first one, which will be mounted. You can then drill down to the Applications folder then drag-and-drop the iDVD folder into the Applications folder on your startup disk. After that, apply the iDVD 2.1 updater you downloaded from Apple’s website.

I haven’t tried burning a DVD yet, but the program seems to work.
