Hi, I just upgraded my home cinema and I currently have a Samsung UE37D6000 TV and the Yamaha RX-V377 A/V Receiver. My question is, how do I know if my receiver is receiving DTS-HD or simply receiving a 5.1 channel signal. It is connected via HDMI Arc from my Samsung TV. Currently on the receiver screen it's showing that it is on PLII Movie setting. I think PLII is just a 2.1 signal split into 5.1 as I've read in the dolby website "Dolby Pro Logic II transforms traditional stereo audio into 5.1-channel surround sound for a seamless listening experience full of presence and depth." Please help. Having a 5.1 Surround System and only experiencing FAKE 5.1 while watching DVDs/Blu-Rays that have 5.1 feels like I'm being cheated. Thanks in advance.
