Hello, new here ..i found this place by looking for some answers. Looks like a great place. Ok, over the last few days i added some new equipment to my entertainment system. A PS3 and a new receiver from yamaha, the RX-v465 for 5.1. Today i just had Dish come out and set me up with a VIP612. Ok, here is my question and how i have things setup and if it is right. The VIP612 is hooked up via HDMI to HDMI 2 (in) port on receiver The PS3 also has a HDMI going into the Receiver to the HDMI 1 (in, listed as Blue ray) And the OUT HDMI from receiver going to the Mitsubishi 65" flat screen. So all my stuff is ignited when i press HDM1 o HDMI2 on the remote. Sounds good, yet is it right for what im doing. The gentlemen who hooked up the system today, said im not getting true 5.1 cause im not using optical line. Yet, it clearly states in the Yamaha manual, HDMI is for video and digital audio. So, im confused. Should i be using Optical out for the Dish box and optical out for the PS3 into the Yamaha receiver? If so, then ill have to grab a think some kind of optical a/b switch as I believe the Yamaha receiver only has 1 optical inline. Also, assuming the setup i am using now is right, what should the Dish box be set to in the setup area. RF mode, or line mode. Right now its set Dolby Digital/PCM with RF mode Anyways, if any of you could help me here. I spent allot on this setup and I want to make sure its working the best it can be. Thanks for reading..... And thanks in advance for your help.
