Query: UltraViolet sucks!

UltraViolet sucks. I made the mistake of buying the Green Lantern with Ultra Violet digital copy, have to sign up with Flixster and then attach your account and sign up again with something and then download an application to your computer to be able to download, otherwise it will not let you. You need the app to play the movie on the app. The movie would give an error message when I tried to play it on any another media player."UltraViolet digital copy can stream to computers, tablets, or smartphones through Flixster. UltraViolet is not compatible with all devices."
