Hallo folks,
I want to backup a dvd as *. iso.
Thanks a Lot.
How to ?

hello, welcome to GhostBSD.

To make an ISO, download any disk burning application such as xfburn or k3b.
Open the application, follow the instructions for adding data to DVD.
Then click burn button. After clicking burn, you should see an option like "Only create ISO". Tick that and instead of burning a disk, an ISO will be created,
