And HERE is the mistake: You need to specify the /dev/cd0
device which gets accessed by the ATAPICAM facility. The
/dev/acd0 device does not understand SCSI commands.

Fully correct. See "man growisofs" for an explaination
of what /dev/dvd refers to. You can either use
growisofs -dvd-compat -Z /dev/dvd=/path/to/file.iso
or
growisofs -dvd-compat -Z /dev/dvd -r -J /path/to/files
if you have devfs.conf point dvd to cd0 - or you simply
specify /dev/cd0 instead of /dev/dvd.

Of course. :-)
Remember: ATA -> /dev/acd0, ATAPICAM ("SCSI over ATAPI") -> /dev/cd0,
and therefore /dev/dvd -> /dev/cd0 for simplified access.
Given you set the permissions correctly, burning DVDs as a
non-root user should be no problem.
