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

32 Something like the "user" option is missing, that would allow your
33 normal user to mount and use the drive, make it:
34
35 /dev/cdroms/cdrom0 /mnt/cdrom iso9660 user,noauto,ro 0 0

47 There's no need for that.

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

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