How to burn S. Leopard Install usb-harddisk to DVD?

[aurora72]

Hello

I made a bootable S. Leopard USB Install harddisk from my S.Leopard Install DVD using Disk Utility's restore and used it to install S. Leopard on Mac mini successfully.

Now I don't have the DVD's anymore and want to use the harddisk to store other things and so I have to erase the harddisk, but before I do that I want to burn the bootable SL Install to DVD but I can't do that.

There seems to be no option in Disk Utiliy or Super Duper to do that. The harddisk is 40GB, but only about 4,5GB (the size of a typical SL Install) is used. How can I burn this to DVD?

Thanks.
