Can DM500HD receive Dolby sound channels

  • I have a DM500HD connected via HDMI to a Sony DN1050 amp. I watch FTA French TV
    on Eutelsat 5.0W [on 11591 V 20000 QPSK]. Up till April all was OK.
    Since then I get both Video and Audio on France 3, but Video only for
    France 2 and France 4. In the Information menu, Service, PIDs, the Sound PID
    shows N/A for Fr2 and Fr4, and 0x00e6 for Fr3.

    I have found this note:



    and this thread:

    Just Sharing This - fransat fta channels from 5 april

    which says the problem is with Dolby 5.1 encoded sound (which ties in with
    the Fr2/Fr3/Fr4 effect), and mentions AC3 downmix (OFF) and HDMI cables.

    With some German boradcats on 19.2E I see a Dolby 2.0 sound channel.

    But my problem seems to be that I get no Sound PID for Fr2, right back in the
    Tuner, rather than in the subsequent audio format decoding.

    Do I need a more modern DB ?

  • The problem is not Dolby Digital (also known as AC3) or with 2.0, 5.1 etc. but the Dolby Digital+ (AC3+) codec used by some french broadcasters.

    As far as I know AC3+ is available on the DM500HD as well, but only with OE 2.0 firmware. So the question is: which software / image version are you using?

    so long

  • Hi

    Unfortunately i have no 500HD but i have a 800se and there the Solution is :
    Go into the Menu /Setup/Picture and Sound/A/V Settings
    once open scroll down to Convert AC3+ to AC3 set this to always
    maybe this will solve your Problem



  • Hello, thanks for your speedy replies.
    The Information, About, says:
    Image:Release 3.2.4 2012-11-04
    Frontprocessor version:1
    Detected NIMs
    Tuner A:BCM4504 (DBV-S2)

    This is the latest image for the DM500HD that I can find on
    Can you suggest an image which will decode AC3+, please.

    The A/V settings menu does not mention AC3+, just the two settings for 'AC3 Default' and 'AC3 Downmix'.

    From your replies I gather that the PID listsing will only show the Audio streams for there is a codec in the Dreambox; is there a way to show all the streams (PIDs) ?

    Thanks so far
