Are you sure that these all have DVD-ROM drives?
The B&W G3 shipped with three different drive options: CD-ROM,
DVD-ROM or DVD-RAM. Although DVD-RAM can read a factory-stamped
DVD-ROM disc, they can not read any recordable DVD media.
The Cube shipped with CD-RW or DVD-ROM.
Recordable DVD media isn't always compatible with DVD-ROM drives, just
like it isn't always compatible with video-DVD players. In general,
the "R" discs will be more compatible than "RW", and "-" will be more
compatible than "+", but these are just generalizations.
Assuming the drive is physically capable of reading the media, then it
may become a file system issue. Standard DVDs (like video discs) use
a file system called UDF. I think Macs can also read and create DVDs
that are formatted with HFS or HFS+, but I'm not sure about that.
some DVD-ROM discs use a hybrid UDF/ISO-9660 file system in order to
be backward compatible with operating systems that don't support UDF
(like Win95). I don't know if MacOS supports this or not.
