The nampage of growisofs lists /dev/dvd in its EXAMPLES section.
That's why I'm using

	link    cd0     dvd

in /etc/devfs.conf, so you can easily use the examples for your
own command purposes. Note that for accessing the ATAPICAM facility,
it may be neccessary to have at least +w for group (operator) for
the /dev/cd and the /dev/pass device the DVD writer is refered by.
Use the camcontrol command to check:

	% camcontrol devlist
	<HL-DT-ST DVD-RAM GSA-H58N 1.01>   at scbus2 target 0 lun 0 (cd0,pass1)

	% ll /dev/cd0 /dev/pass1
	crw-rw-r--  1 root  operator    0, 116 Sep 10 10:10 /dev/cd0
	crw-rw----  1 root  operator    0, 115 Sep 10 10:10 /dev/pass1

	% ll /dev/dvd
	lrwxr-xr-x  1 root  wheel            3 Sep 10 10:10 /dev/dvd@ -> cd0

In the last case you mentioned, growisofs would create an ISO-9660
file systen on the DVD which then contains one .iso file. That's
possible, but won't create the result the OP wanted, I think.

The burncd command usually refers to burning CDs, not DVDs, allthough
it may be possible that it can be used for DVDs, too. But I'm not
familiar with it anymore, because I use growisofs for DVDs and
cdrecord / cdrdao for CDs; both of them use the ATAPICAM facility.
