do you think that this user

That can cause a block device to appear to be read-only.
Well if it does cause such effects then it is surely worth a
try to disable it.
udev and hald are the natural enemies of burn programs.
We compete for the same hardware and the OS normally does not
care about arbitrating.
Nevertheless, i would have expected that the block device
driver gets more respect by udev.
Here's one hit from google
(different symptom, but solution would be the same):
http://unix.stackexchange.com/questions/1399/dvd-drive-constanly-spins-up-down-when-idle
It advises to try:
udisks --inhibit-polling /dev/dvd
or
udisks --inhibit-polling /dev/sr0
Do you have more information about udev causing read-only optical
media ?
Have a nice day :)

Tried that. With no media in the drive, I started udisks then inserted a
blank disk and tried to mkudffs on it (in a different root terminal). It
failed with the same read-only error.
