I was surprised that the video of the two formats were that close. I can only imagine that that gap will close even tighter over the coming years. Too bad the Movies Anywhere audio is such a disappointment. You'd think that would be easier to send than the video.Glad to see you still have the Kaleidescape unit for these comparisons. One wonders if there would be any noticeable difference between the Kscape version and the 4K disc. Based on this review, I would guess not.Scott
