With the newest update, I find that I cannot play my mkv files anymore. The video codec is MPEG-H Part2/HEVC (H.265) and the two audio codecs are Opus Audio and mp4a.
It used to play these files just fine, but now when I open them up in Skybox, it freezes on a black screen for a few minutes before shutting me out of the app. A fix would be greatly appreciated.
