Hi All... Here is my question: I bought a Samsung 4k ultra HD smart TV, then bought a Sony 4k Ultra upscale Blue Ray Player, last, I bought a 4k Ultra HD DVD movie. When I put the movie disc into the player, it says, "Disc not found", or it will not run it or recognize it. It will, however, play blue ray dvds, and regular dvds. What am I doing wrong?
