OK, like I expected - there is no /dev/dvd but only /dev/dvd1.

Because you had a valid rules file:

I'm not sure if the filename needs a ".rules" extension (the udev man 
page doesn't mention it) but your backup is located in the directory 
"/etc/udev/rules.d/" where udev looks for rules files and it does have 
the ".rules" extension. I would suggest you put your backup in another 
directory like e.g. "/etc/udev/backup/rules.d/".

I had a look at the script /lib/udev/write_cd_rules and if I understand 
the comment at the beginning correctly, it will only create the file 
"/etc/udev/rules.d/70-persistent-cd.rules" if there is no rule for the 
drive. Unfortunately your backup had the rules so there was no need to 
create the standard file.

So far I think it all looks consistent to me _but_ I have no explanation 
for the fact that you could play the dvd when it was in the drive at 
startup.
