I use my phone to watch movies from time to time and some of my series are in .mkv files. I use MplayerX to decompress and watch these files. I recently watched Django Unchained on my phone (in .mp4 format) and it was playing smoothly, however whenever I use .mkv files the picture seems to lag and sometimes the audio doesn't synchronize with the video. Is this because of the app or is it too much for the phone to handle?
Note: Each of these was in 720p.
