I've just completed setting up a new Media Center with a Black Gold 3600 card which has dual DVB-S and dual DVB-T2. My MCE is connected via SP/DIF optical to a Denon AV receiver. This is all now working fine. I notice however that BBC HD channel 108 on Freesat is transmitting in Dolby Digital (as indicated on the Denon) but if I switch to BBC HD channel on DVB-T2 (54) there is no indication and the AV receiver reverts to Stereo. When I look up info on DVB-T2 it seems that Dolby Digital is 'mentioned' a lot but as I said above, my experience does not bear this out. Are the HD channels on DVB-T2 only stereo? Thanks. Brian.
