Hello, I am trying to play one specific mkv file on Zidoo Z9s. Unfortunately I see glitches and noises on TV screen. I don`t know why I cannot play it back. I tried to use mkclean tool but it doesn`t make this file playback correctly. I tried to change file profile, but none of these methods worked. How can I fix the playback of this file on Zidoo Z9s.
