Right out of the box Ubuntu Gutsy 7.10 does not play encrypted DVDs. All most all of my favorite DVDs are encrypted by the big bad cooperations. It is hard to rip these DVDs if you can’t read them to begin with. This guide will not tell you how to Rip DVDs, it is just linkage to being able to play them on Gutsy. I will write a guide for ripping later.
This is a very easy fix, but you have to choose which way you want to fix this.
I encourage you to test these out so you can start watching quality movies. Enjoy!
