I have become a bit confused as to what receiver i need to buy, to the extent i am now wondering if i need one at all, is it possible to have 5.1 surround sound with just the TV (probably panasonic 42pz81 or Sony 40 w4000) a PS3 and a set of SFX tannoy 5.1 speakers.If the broadcasts ie: Sky or DVD supports 5.1 can the sound not be run direct from the PS3 to the speaker system, or from the TV to the speaker system, maybe a stupid question but just thinking out loud.
