Here is a diagram

I've been backing up my Blu Ray to mkv files using MKVMaker and I've been keeping most of the audio tracks that are in english. When I go to play the mkv file on the revue, it plays the narrated audio track that narrates everything in addition to the original audio track. How do I get the narration off? It does not do this when I play the file in windows media player on the pc. Any insight? I'm using serviio because it is the only one that lets me see the files on the external hdd (I've tried TVersity, TVmobili, playon, and windows media player server).
