I have a Sony KD-65XD8505, and I tried many different players (Standard/VLC/MX PLayer). But when I load a mkv file somewhere after an hour or 2 hour it just crashes. I have tried remuxing the mkv with MKVToolNix but it didn't help either. I am playing them through a usb3 hdd attached to the tv. Does anybody know how to fix this it's kinda driving me insane.
Have you tried plex or.kodi ?
