This firmware and last, I get constant crashing with some movies. Not sure if the zidoo device is corrupting my files, but they worked fine 2 firmware ago. One film I'm trying to watch is A Quiet Place Part II - Dolby Vision File that I made using MakeMKV. It did similar behaviour with my Halloween Movie Series Dolby Vision Files. It's rather something with the player is bugged or it's corrupting my mkv files.
