Now this is where it gets fun - there's only two ways TOSLINK can carry surround sound: analog encoded Dolby Surround on stereo PCM (down-mixed audio); AC3 encoded surround on binary raw stream. My HDTV takes the surround from the HDMI and AC3 encodes it, then dumps the AC3 over the TOSLINK to the digital receiver. Supposedly, really high-end equipment can do the same thing with DTS encoding, but I've not seen this (way out of my price range).
So it really goes like this: PS3 sends 8.1 surround to HDTV via HDMI. HDTV encodes the 8.1 into 5.1 AC3 and dumps that out the TOSLINK to the receiver. The receiver decodes the AC3 into 5.1 which goes out the five speaker and subwoofer. Let me tell you - it sounds FREAKIN' AWESOME!!!!!
Note, when I say the PS3 sends 8.1, I mean it sends UP TO 8.1. What it really is will be up to the movie. An old DVD will be plain linear PCM stereo. A new DVD will be 5.1. A BD may be 5.1, 6.1, 7.1, or 8.1. HDMI will handle all those.
