Your CD/DVD drive will appear as /dev/sr[some-number]. Some systems have 
two drives, so they'll be /dev/sr0 and /dev/sr1. Depending on
how your machine was installed, your first drive may be /dev/sr1.
I've not sorted out why exactly, but I've seen it.

Usually the udev rules also set up appropriate symlinks in /dev to
point at the devices. For example, /dev/cdrom will generally point to
the appropriate device:

	root at prophead ~]# ls -l /dev/cdrom
	lrwxrwxrwx 1 root root 3 Jan 15 11:23 /dev/cdrom -> sr0

It should also create a /dev/dvd symlink which will also point at the
correct device, but none of my F17 systems seem to set up /dev/dvd*
links anymore (boo!).

Also note that if you have two drives, you'll still have some questions
as to which drive is what. The system will have /dev/sr0 and /dev/sr1,
and quite possibly symlinks like /dev/cdrom (pointed at /dev/sr0) and
/dev/cdrom1 (pointed at /dev/sr1).

After installing blank media, you can look at /var/log/messages or the
output of dmesg to see which drive saw the new media.

My recommendation is to feed "/dev/cdrom=/path/to/iso/image" to
growisofs and see if that'll get you anywhere or stick with brasero
to burn your disks.

Yes, it's confusing if you've not dealt with it before.
