 Boy, you sure pick the most difficult burning program to use.  Just
read the wodam man and haven't a clue how to burn an iso image.
As another person has said, the nautilus right click option has worked
for me and others without fail.  K3b is also good and easy to use and
that's what I would recommend. If you can't burn a good iso image using
nautilus or k3b then maybe something is broken on your cd/dvd writer.
