So I've always wondered why they have advertisements on DVD's for buying Blu Rays, I understand the marketing concept, but they show little clips of movies during action sequences and then say things like "stunning picture quality" "5.1 Surround" etc... are you supposed to look at that clip and go "WOW! THAT REALLY DOES LOOK BETTER!" before realizing it's being played on a standard DVD and there is no difference in what you're seeing right now?
