I have a Phillips 47" Tv, a Panasonic 5.1 Home Theater in a Box, an Xbox 360, VHS, and Cable Box. I am quite new to the Audio format. My HTIB does not have a optical port only HDMI out. I figured I need to reciver that can take in a optical port and hook my HTIB speakers and subwoofer up to the reciver. Would any reciver that takes in 5.1 speakers do? Anyother suggestion or help to this would be appreciated.
