Q I'm a big proponent of physical media and was an earlier adopter of the Ultra HD Blu-ray format. I understand that certain movies may have been shot in 4K or higher resolution (or on 35mm film, which provides enough detail to scan at 4K), but then mastered for release from a 2K digital intermediate. I’ve been able to appreciate the benefits of the Ultra HD format almost immediately thanks in large part to high dynamic range, but am bothered that some disc titles are mastered at less than Ultra HD resolution. It seems like we’ll soon be seeing "New 4K Remaster" versions of movies previously released in Ultra HD. What’s the issue here? —Jason Acosta

Q I was recently in Best Buy asking about speakers for Dolby Atmos. I was told that to get Atmos I would have to change out my current setup and buy a new set of Atmos Speakers. Is that true? —Wendell Blue

Q Do the preamp outputs on A/V receivers work as well as those on a standalone preamp-processor? What functionality does one lose when using pre-outs on a receiver? —Ravinder Dhawan, Watchung, NJ

Q There are two-dozen or so Ultra HD Blu-rays available for purchase, with many more hopefully to come. However, none of the UHD Blu-ray releases are available in 3D, even if the theatrical version was in 3D. Do you know if there are future plans for 3D Ultra HD Blu-rays, or has the home video industry decided to kill off 3D for good?
