However, I'm still having issues with a 1080p mkv file. It recognizes the file, but when I press it I get the "Cannot Play Video" error. Also tried to open the file with ES File Explorer. Same error.
Is there a good functioning alternative media player? I.e. in the shared DropBox?
Really hope someone can help me out, because I need this mean machine to play 1080p mkv files

Many thanks in advance!
