Video Issues w/ Side Loaded Kodi topic

So I decided to pick up AFTV a week ago after reading so many good reviews about the device and how well it runs Kodi, but I am having an issue running certain MKV files with dual audio. When I try to play the videos Kodi either crashes to the FTV menu or restarts the whole device. I tried to disable the accelerators in settings and the video starts to play with stuttering and no audio. Anyone know what could be the cause of this and is there a fix available.

BTW I'm running Helix 14.0
