How to create a bootable DVD with SuperDuper on it
 

Hello,
because my old PPC iMac cannot boot from USB drives, I would like to make a bootable OS X DVD with SuperDuper on it, for restore purposes.
I know how to create a minimal OS X with SuperDuper on an external hard disc, but how can I put this image on a DVD and make it bootable?

You can't, really. But you can just use your OSX DVD, as explained in the User's Guide...
