I did some searches and believe I found the answer I'm looking for, but just want to double check with the experts on here.
So, I have a PS3 slim hooked up to my HDTV via HDMI. I then have the TV hooked up to my older Sony DVD home theatre system via an optical audio cable. When I select the Video 2 input on my Sony receiver, the PS3 sound comes through the speakers just fine, but am I getting true surround sound here? Or am I just getting 2ch simulated to surround? If the answer is only simulated surround because of 2ch only, does this apply to other devices such as a Roku box as well? I want to utilize the full potential of the PS3 sound, so I'm thinking I just have to upgrade to one of the newer surround sound receivers.
Also, I've noticed that these newer home theatre systems have multiple HDMI inputs and then one main HDMI output to the TV. Does this mean I can just hook up a PS3 directly to the receiver via HDMI and then the receiver to the TV via HDMI and get video and surround sound? Sorry if this is a basic question, but I'm behind the times here... Thanks for the help.
