i want to buy a home theater system. its a bluray/receiver. one of those all in one type of system. im a bit confused as to how home theater system works. for example the sytem has 2 HDMI IN 1 HDMI OUT 1 Optical Audio 1 Component Out so basically the HDMI out connects to the tvs HDMI right? then say i have an apple tv and ps3 both connect to the IN? but if i connected to the home theater receiver then how do i get picture? im confused. so then what if i have another HDMI device, that would go to the tv since the receiver doesnt have any more, but then again how would i get audio since its not connected to the home theater receiver. sorry im really clueless about how it works. Please someone clear it up for me.
