How do you make sr0 RW instead of RO ? When I put a CD/DVD in the drive and mount it with the path /dev/sr0 which is my DVD it always mounts RO. I can't write to anything.

use the command:

umount /dev/sr0

I've found myself that auto-mounting of media by desktop environments blocks write access rights to burning programs. Issuing that command allows them to regain full control and burn to the drive.

As I understand it, that means, when you mount it, it's mounted ro. That is usually what the user wants when they mount a dvd or cd they want to read or play from. If the user wants to write to the media, then usually he/she uses a program such cdrecord, wodim or growisofs as root ( which provides access to the hardware) which will write to the medium. Your query may however be asking something else.

I think I remember RH 9 and you could mount it RW. Maybe things have changed or I don't correctly remember.

The kernel only supports read-only isofs mounts.
Similar for the fuseiso application.

I have serious doubts that a writable iso9660 is possible - it just wasn't designed to support it. You *might* be able to append, but deletions are ... problematic.

Doing this on top of a non-block I/O medium is pretty hard.
