Hello, Norman.

The 'old' /dev/dvd was a symbolic link created when you originally 
installed Ubuntu. The Ubuntu installer detects your hardware, and sets 
your /dev directory up accordingly. However, every time you boot Ubuntu 
it checks to see if anything has changed. If it has, "udev" remembers 
the old device in case you use it again, and creates a new symbolic link 
for any new devices it detects when you boot - In your case /dev/dvd1.

The place where "udev" stores this 'persistent' information is:

   /etc/udev/rules.d/70-persistent-cd.rules

You can edit this file to make "udev" point /dev/dvd at your drive if 
you want. However, it might be a bit confusing if you've not done this 
sort of thing before. My advice is to have a look at the file anyway, 
and see if you can work out what happened to your /dev/dvd. If you post 
the contents of the file here, we might be able to help you work it out.

Bye,

   Tony.
