Hi all, I burned two identical DVDs in the finder (10.3.9) using my G4733, with a Pioneer DVD-RW DVR 106D Drive. They both read just fine in the same drive, but nobody else in my office can read the disks. I've tried a Pioneer 104RW (OS9) and a 104R (OS 10.2) drive. Neither can read them they just sit and spin for a while and eject. What's the problem?
