How can I stop a non-admin user from using the DVD drive (specifically burning DVDs if possible, but all access denied is fine too). I've tried removing them from cdrom group but this did not seem to change anything.
My DVD drive appears to be /dev/sr0 and doing right-click>properties>permissions seems to show Owner:root Access:read and write, group:cdrom, Access: read and write also groups <myNonAdminUser> shows he is not a member of cdrom so how can he access the DVD drive? Could it be something to do with my fstab file?
