How to go about digitizing my movie collection?

I'd like to digitize all my DVD's & Blu-ray's and would like to know how to do so. Also how do I get digital content like movies that I actually own, like I've read that if you buy digital stuff through Amazon or Vudu that you don't actually own it, you just own the license to watch it? I'd like to be able to view all my content even when I'm offline. How do I do what I just said?
