I experimented a bit more and the bug was indeed caused by pmount and gnome-volume-manager deferring the mounting process to mount. Then mount was blindly following the uid and gid stored on the DVDs. Once the /etc/fstab line is removed, pmount and g-v-m take over and they forcibly set the uid and gid of the files, hence hiding the flaws of the DVDs.
There is still a bug/feature somewhere else (in debian-installer perhaps?), as the /etc/fstab line was added by software. (I would never have called a mount point cdrom_0_ and added symlinks all over the place.) But that is a story for another time and report. Sorry for the noise, I should have been a bit more careful.
