Well, I actually have 2 questions. First, I'm just wondering if the DVDs, which read "Mastered in 4K" have a better picture or have better sound than just a regular Blu Ray disk played on a 4k TV. Second, since most, if not all, 4K TVs upconvert, why would anyone buy a something like Sony's new BDP-S7200, which is supposed to upscale to 4K, access to Netfix, SEN, etc? If someone owns a 4K TV and already has a Blu Ray player (not this particular one) what's the benefit of owning this new Blu Ray player? 4K TVs already have a lot of these features built-in. Unless someone owns a different brand of TV, it'll give them access to SEN, other than that, I don't see the benefit. And to combine the questions, if someone were to watch Spiderman 2 Mastered in 4K on this new Blu Ray player, will it look better, worse, or the same as watching it on the FMP-X10?
