Ok I've got my CD burner on an upgraded beige G3 (to a G4 400) but only running OS 9.2.2 The CD burner is SCSI. I have a Powebook G3 running OS X 10.2.6 and have purchased several iTunes and want to burn a CD. Do I: 1. Take the plunge and upgrade to OSX 10.2 with the beige desktop (my main work machine which makes me hesitant in case I run into compatibility problems) 2. Try to figure out how to convert mp4 files to mp3 files so I can burn the disc. My main problem with upgrading is trying to find drivers for the USB/Firewire card and the CDR drive. Any ideas? Thanks!
