Well, let me clarify.I don't know about the "everyone will agree" part. People here seem to go out of their way to say they can't see any difference between DVD and Blu-Ray. And then you've got those people who stretch their 4:3 pictures to fill their widescreen TVs who are on another planet all together.
"Everyone will agree" if they watch Blu-Ray under the right conditions. The problem is you pretty much need a giant TV and be watching from the right distance in order for the picture quality to be noticeable. I could buy a Blu-Ray disc and play it on a 20" TV and probably won't notice a damn thing.
I notice a major difference just using the HDMI upconverter on my DVD player. I'm sure that Blu-Ray will look even better. But the question is: do I care?
I don't. DVD is fine for now, and it will be until Blu-Ray disc prices drop...or until I can start renting Blu-Ray discs at Hollywood Video.
