I Have ripped most of my bluray movies using Makemkv. The issue I have is that with some the video lags behind the audio. Im assuming this is a issue with the encoder as all the files that are effected play fine with my Mac with VLC player. As far as I can tell the issue seems to be mostly on WB movies. recently I have switched though all the Kodi OS's to see it the issues exist with them and they do.
