its no more complicated than this as i have my PS3 set up with my surround sound.
HDMI ----> TV directly
OPTICAL------> Surround sound optical input in dvd player or subwoofer.
on the surround sound controller you need to select the correct input selection, ie AUX/DVD/SKY/RADIO etc.
The surround controller will either be your subwoofer if the speakers are a stand alone speaker set that you can use without the dvd player or it will be the dvd player. whichever one has the optical input port.
