john9159,
Welcome to LQ.
In order to get Xfburn working you may first need to go into Terminal and installed Restricted Extras:
Code:
sudo apt-get install ubuntu-restricted-extras
Why do you need to use DBAN in particular?
Could you not download and burn a gParted .iso onto a disk from:
http://sourceforge.net/projects/gparted/
If on the other hand you are trying to totally wipe a disk securely then you need something other than DBAN.
