Hi everyone this probably a ridiculously easy question, but i'm a man of a lot of questions, big and small. Anyways, if i buy a stereo receiver and a pair of speakers, and hook up the receiver to the tv, will the sound play through the speakers when i hook up ps3, xbox, cable via hdmi to the tv? Being that a stereo receiver doesn't have hdmi. Would it be easier for me to buy an a/v receiver, even though i'd only have stereo speakers? Also, if i had a 5.1 receiver with 80 watts per channel/5 channels, would that equate to 200 watts a chanel for 2 channels? THANKS everyone, and excuse the newbie in me.
