I need help. What is the best way to configure these components. I have a Hitachi 42" plasma 42HDT79 A HD cable box from comcast A Sony Dav-C770--dvd/receiver surround sound I did a little research and it seems the IEE1394 hookup is the best which all 3 components have one of so I cant hook up all 3 simutaneously with that method. I want to use the Sony as a surround sound for both the dvd/tuner and the tv. What is the best way to hook these up to one another? ie: tv-cable box? Tv to Sony? or Sony to cable box. Is there one way better than the other? Thanks
