This may be an old (and/or stupid) question, but I'm a little confused about HDMI and optical audio connections. Right now I have component video running from my 622 to my Panasonic HDTV and optical audio from the 622 to a Sony surround sound receiver. I've been reading about HDMI and thinking about changing to HDMI to connect the 622 to the television. Will the optical audio output to the surriund sound reciever still work? In other words, will connecting the 622 to the TV with an HDMI cable disable the optical audio output to the surround receiver?
