I have a number of movies on a portable hard drive connected via USB. They play fine, except that the digital out to my A/V receiver is always PCM instead of Dolby surround. I looked for a setting commonly found on TVs that sets the digital audio out to a choice of PCM or Dolby, but could not find one on my UT50. any ideas? The envelope is MKV MP4/AC3.
Thanks for any help.
