Ubuntu v6.06

I am trying to use a bash script to compare a file on a DVD to a file on
my hard disk.

The command:
cmp /media/cdrom0/file1.junk /home/user/file1.junk

The permissions for /media/cdrom0/file1.junk are:
Permissions -r--r--r--

The permissions for /home/user/file1.junk are:
Permissions -rw-r--r--

The error: line 86: /media/cdrom0/file1.junk: Permission denied

Is there something special that I need to do in order to read a file
that is on a DVD from within a script?

This works from the command line.
