Well, its pretty obvious that root only can mount, and you're using
k3b without root privileges (as a normal user), dus you can't mount
it, nor use it.

Something like the "user" option is missing, that would allow your
normal user to mount and use the drive, make it:

/dev/cdroms/cdrom0   /mnt/cdrom   iso9660  user,noauto,ro 0 0

There's no need for that.

You do that as root, don't you, and besides, a cdda player don't need
to mount cdroms, it uses the device itself in read-only mode. But to
copy files, you need to mount, and to mount you must be root, or
change the fstab file as stated above.

You should be able to do all you can do with your drive, in your case,
I believe you can read cds and read dvds, but as far as I know, you
can't burn cds, its a dvd drive, not a cdrw or a combo. (at least
considering the name, I may be wrong)
