I have the same problem.  I first wrote about it several months ago 
here: http://www.gossamer-threads.com/lists/mythtv/users/410784

Here is another thread with what I believe is the same problem:

Playing the same .mkv file with other media players with DTS passthrough 
enabled works fine.

A workaround is to enable the AC3 checkbox in the audio settings but not 
the DTS checkbox.  It will then internally decode the DTS sound and 
reencode it to AC3.  At least I believe that's what it does from reading 
messages on this list from JYA.
