I still use my Tag McLaren AV32R, which has plain vanilla DD and DTS. It also has DPL II Movie, which I utilise for either 2 Ch PCM coming in from the TV (the processor can't deal with HE-AAC, & has no HDMI inputs, so uses audio return from the TV), or DD 2 Ch (some stuff on Netflix, for example). Nowadays, I understand DPL II (and associated) isn't on any receivers/processors anymore (or very few). So what do you use to process 2 Ch PCM or DD 2 channel stuff? What options are there for turning a two channel signal into faux five channel, so to speak?
