Query: great movie great service BUT only got to see half

Amazon is great for the pre-order price guarantee, and offering a free digital copy b/c of the delay in shipping but unfortunately, my copy weirded out after 20 min into the movie, the sound was on but no video. Don't know what happened. Guess I'll just have to wait for the dvd to get here
