ONKYO HT-S5100 Black 7.1 Channel Home Theater System

Pros? Cons? Will this give me the option of watching blu ray with full HD audio quality? And what does it mean when the author of the text below says, "only passthrough?"

"Cons: Learned my lesson the hard way... this is not HDMI through the surround sound, its called "Passthrough" which means that video and audio are passed through the HDMI like its a switch, the audio is not processed by the receiver and is sent through the HDMI to the HDMI source. I was bummed about this because I wanted to have HDMI digital audio being processed . Lesson learned, but its okay, i ended up getting a couple of optical cables and that is how the sound comes through from my HDMI devices. Kinda strange tho they have 2 optical in's but 3 hdmi in's."

What do I have to do to get full HD audio on this system? I am using the ps3 as my blu ray player.
