I recently gave K9COPY a try, it’s supposed to be the Linux equivalent of DVDshrink for Windows. It certainly looked the part, but when I ran it with a disk I wanted to back up it ran for a short while and then crashed

Looking at the output of dmesg revealed that the disk was having trouble reading the encrypted disk:
[235.097347] sr 5:0:0:0: [sr0] Add. Sense: Read of scrambled sector without authentication

It was at this point I realised that I had not yet installed the restricted media packages (also needed to play DVD films). So…
sudo apt-get update && sudo apt-get install libdvdread4
sudo /usr/share/doc/libdvdread4/install-css.sh

“That should do it” I thought! But no luck, it still didn’t work. I searched synaptic and installed some other packages that looked like they should help but still nothing… The disk would not play or back-up.

In the end deleted the contents of ~/.dvdcss and amazingly, it worked!

So if you’ve followed the Ubuntu instructions and still can’t play or back up a movie DVD then you might want to give this a try. I’m posting it here because it’s not an obvious solution and I’m sure I wont remember it next time I re-install my system.
