Comment(by anonymous):

 Adding some further comments:
   - Setting upmix to "Best" but still not works for all channels.
     In my case with the "Discovery Science" channel I got this weird
 behaviour.
     Looking in log from mythfrontend

      This make's me believe that this channel is sent with MP2, 1 channel
 only (Mono) and   maybe that
      is what causes the problem.
