I think the DVD at the end of your command "kaffeine -d /path/to/backup DVD" should be removed. "kaffeine -d /path/to/backup"
-d, --device <argument> Set Audio-CD/VCD/DVD device path (e.g. /dev/cdrom) All that would be necessary would be the options (-d or --device) and the argument (/path/to/backup). Does that work? -- kaffeine ignores --device https://launchpad.net/bugs/56150 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
