It is even easier to copy DVD’s with encryption or Copy Protection on Ubuntu than it is on Windows. Just follow these steps and you’ll be on your way.
1. Install libdvdread4 by following the section here for “Installing support for proprietary DVD formats”
2. Install a program for Coping your DVD’s. I highly recommend K9Copy, it is probably the easiest to use as well as offering a few features for more advanced users. K9Copy is available from the Ubuntu Software or Synaptic Package Manager. Another program that can be used is dvd::rip.
Now you should just be able to insert a DVD into you computer and copy it!
But please not that doing this is illegal in some countries, and you would be the one responsible.
