Just picked one up yesterday. I hooked it up via hdmi to soundbar and hdmi to TV. I see it displays 5.1 on the display and then says pcm. I was watching transformers and it shows to have audio in dts. In the options field, I select 5.1 dts, but on the sub, it displays 5.1 and then displays pcm. It does not show it broadcasting dts, even though it shows to decode dts in the manual. Am I doing something wrong?
