Hi i have a sceptre 32" 1080p tv screen and the sound sucks i want too hook up a surround sound system but im wondering most come with a dvd player blue ray player with it does it matter if i get blue ray or dvd on the receiver since i will be playing my movies through my ps3. Also my setup right now is my ps3 is plugged in with a hdmi cable too my tv should i leave it like that and then plug a optical cable from my tv too my surround sound or hdmi? and does sound quality matter if i buy one that comes with a dvd player or blue ray player? I dont really need a dvd player or blue ray player on the reciever do they sell them without that on it as i will be watching my movies on my ps3 thank you for any answers. sorry for any grammar errors im in a hurry
