i thought PLIIx and PLII was the same when i post this threat. now i know it's two different things now that you clarified it. and yes i followed the instruction at least i think. i hook up 2 frond, 1 center, 2 back and a subwoofer to my avr and i can hear sound from all of the speakers if that what you mean by getting 5 channel sound at all. My BD player, cable sat-top box, x-box, Apple-tv, and Playstation goes to avr by HDMI cable and avr output to TV by HDMI cable.
Ps; i'm sorry if i didn't answer your question or give enough info coz i am really new to this area but i'm quick learner and i love to learn new things.
