setting device for DVD drive

[Rob Owens <rowens@ptd.net>]

I just replaced my old DVD drive on my Squeeze system.  It used to show
up as /dev/dvd (which may have been a symlink to another device -- I'm
not sure).  The new drive shows up as /dev/dvd3 which is a symlink to
/dev/sr0.

How can I change it back to /dev/dvd?  All my dvd-related software (vlc,
mplayer, etc) is looking for /dev/dvd.  I'd rather change the device file 
for my new dvd drive than change the config for all of my software.

Any help would be appreciated.
