Arrow are saying there is no problem, but the owners of the most popular 4k player on the market beg to differ
It's not all Panasonic players, it's just the UB820, and it doesn't play the Dolby Vision version of the film, just a black screen with the soundtrack playing as normal. I only have the basic UB150 model because I got it region free modded and the 820 was too expensive at the time
