Well I think you have to either create the device in /dev or use a different one. I'm guessing. The first thing I'd do is check all the cd devices you have using the mount command ie "mount /mnt /dev/cd1" or what ever your distro calls the CD. Make sure your checking the web and news groups for answers. I have not used your distro so I'm flying blind.
