want to rip your dvd’s on your ubuntu box, ive always used handrake on my mac and you can use it on ubuntu as well, nice and easy to use to get this up and running get a terminal up and use the following commands
sudo add-apt-repository ppa:stebbins/handbrake-snapshotssudo apt-get updateAnd finally the installation:
sudo apt-get install handbrake-gtk handbrake-cli
note this doesnt work on 13.04
