First of all, I would like to thank Warner for using the Ultraviolet digital copy. If they had used the classic iTunes digital copy, I would've just used that and moved on. But since Warner used Ultraviolet that is not compatible with iTunes, I was forced to educate myself, and now I have a DRM free, hassle free, high-def digital copy of my own.
How? If you have a blu-ray drive on your computer, google DVDFab HD decrypter. It's a free program that will allow you to rip blu-ray movies. You can selectively rip just the main movie without the extra foreign language audio and what not. Then google Handbrake. This program will allow you to encode your blu-ray rip into an iPhone/iPad/Apple TV compatible format. Obviously encoding from a 1080 source takes time, but patience is a virtue, and you'll get a high-def digital copy of your own! Hint: use 720p for better compatibility with Apple TV and non-A5-equipped iDevices.
If you don't have a blu-ray drive, than simply follow the same procedure using the DVD, and you'll have your own standard def hassle-free digital copy.
So, again, I would like to thank Warner. Now I have learned how to make my own real digital copy of the movies that I paid for.
