Contact Jake and see if you could arrange to get a copy on USB instead.

Did SL (single-layer) DVD-ROM readers exist? I wouldn't have thought such things would comply with DVD specifications. More likely, the drive will handle DL (double-layer) DVD-ROM, but may be incompatible with DL DVD-R and/or DL DVD+R (whichever format the PPC DVD uses).

Heck yes, for many, many years. I truly doubt the G5 came with a DL drive, though the drive may have been replaced with a newer one along the way.

You comment about the media is a definite possibility as well. Modern (that is, recent until these too started to become extinct) DVD drives can read and write just about any kind of media, but many earlier drives definitely were limited to only -R or +R media.
