How to make ISO file from DVD (protected) – [Linux]

I like do a backup of all my DVD’s and play them with VLC from a shared folder. So, how backup them?

Requirements:

$ sudo apt-get install dvdbackup genisoimage

Steps:

First you need to retrieve all keys to decrypt the DVD.

$ dvdbackup -M

After the starting copy of dvdbackup you can stop the execution (Ctrl-c) and run genisoimage

 $ genisoimage -dvd-video -udf -o movie.iso /media/DVD
