    I have reported the following problem to support conceiva com who are looking at my problem currently

    When I play the video Casablanca 1942 with GOM player or Media player, it plays the actual movie and the first audio stream spoken by the movie players

    When Mezzmo plays the video on my Panasonic TV, it plays the third audio stream that is spoken by with Rudy Behlmer a person presenting the documentary history of the movie whilst the actual video is screened.

    support conceiva com advised that the "first" audio stream should be played

    No, that didn't work either. The audio is still being identified as Dolby and causes my AV equipment to play it that way.

    I'm using the same Bluray player as you (Sony BDP-S370) and unless you're using another build of the software does your unit report that every file is in Dolby?

    Yes, it does, but I don't see a problem with it playing as Dolby - the sound is there both via the TV and via a home-theater setup.

    Thanks for your assistance. At least I now know that it's not my equipment that is causing the problem.

    Will you be releasing an updated program build and/or FFmpeg build anytime soon?

    Yes, we've got an update being tested now - I don't know if it'll be released tomorrow (Friday), but early next week looks likely.
