When I play any mkv 4k the player tries to start it, the sound is heard about 4 seconds, without an image, and it hangs.
You can only exit by pressing the "top menu" key to return to the dune browser (the bottom of the menus is lost and remains in black), but no longer plays anything if it is not reset from the back on / off button.
In mkv 1080p or below everything is perfectly reproduced.
