I am interested to see if anyone here has experienced a similar problem to the one I find with my Panasonic BD35 and my Onkyo 606 receiver. My player is set to bitstream and secondary audio is set to off. I choose Dolby TrueHD from the disc menu but my receiver indicates only a Dolby Digital signal, not Dolby TrueHD. All my settings are correct as far as I know. I have tried speaking with tech reps from Onkyo and Panasonic but it is useless. The audio doesn't sound bad by any means but I am concerned about not getting what I expected, which is the ability to hear the Dolby TrueHD and DTS Master soundtracks. Can anyone lend a hand here? Thank you, Laurie.
