This is my second Sony. I finally got a 4K player last year and got the Sony UBP-UX80, and certain titles kept pausing and/or tiling. Got some great advice here to turn off Auto Home Network Access and remote start and software update. Worked fine after that, except on Ready Player One. Flash forward to December, and a new firmware update which caused the player to power off and on at random. We bought a new one at Best Buy, we were leaning towards a Samsung with Dolby Vision, the seller who was a "Sony Expert" per his name tag, got us to go with the Sony UBP-X700 which also has Dolby Vision. Same thing has now happened, and I have everything turned off as well as Quick Start, and that's what the Sony rep told me to do when I contacted them. NOTE: This is not with every disc, it seems like it's primarily 4K discs that are from Warner Brothers, or Disney. Just got done watching my second viewing of 2001 and both times it pauses and freezes when HAL is being shut down, and during the long pan of the planets and the monolith during the Jupiter and Beyond The Infinite sequence. Anyone having issues like this? The discs are totally clean and I have the right high speed HDMI cable etc. Are all players like this? It's really starting to put me off 4K UHD, but I have no issues with discs from Paramount, Universal, Lionsgate, or Sony Pictures Home Video. HELP PLEASE!!!
