That's because it is! Re:

It's a 4th Generation DVD-RAM drive. They have the same capabilities as a 2G+
DVD-RAM (2x)
drive and a 1G DVD-RW (2/1x R/RW) drive. Re:

DVD-RAM works _natively_ with Linux (has since 1998). In 2.4.x, you can use
the /dev/scd0
(block) device _directly_ in /etc/fstab:
/dev/scd0 /mnt/dvdram auto noauto 0 0
That should work _regardless_ of whether the media is read-only or read-write.
I'm also curious if you can use DVD-RW disks, or even CD-RW disks, directly as
well via this
method? [ I haven't had a 4G DVD-RAM to play with yet ] I assume so since it
uses the DVD-RAM
firmware for access.

That's because the drive has DVD-RAM firmware. You need to get ProDVD to
record with this drive
to the /dev/sg0 (character) device. CDRecord 2.0 with patches may work as well
(I don't know,
haven't tried myself).

Kernel has _nothing_ to do with /dev/sg0 (character) other than providing the
device node and
interface. 100% of the "brains" for "recording" is in the CDRecord/ProDVD
software.
Now the kernel _does_ provide random-access/packet-writing support for DVD-RAM.
That's
where the /etc/fstab entry I wrote above comes into play.
