Dolby digital from freesat
i have two freesat feeds, one via a humax box and one via a Panasonic gt50 tv. I've been trying to get Dolby digital through either to work but can't seem to get it to. I have my ps3 connected to my amp via optical cable and that works fine. If I move the cable from the ps3 to the humax or the tv I can't get Dolby digital feed even though the program's show they are Dolby digital recorded. Any got any ideas, can you only do it over hdmi from the humax? I checked the settings and its set to Dolby digital.
