In reply to:
sushi, are you saying your pio knows or remembers if the source is a dvd or a dvd-a on it's own?
Dan, not really. You do have to tell the receiver each time whether you want to use the multi-channel analog input or the coax/optical digital input. The receiver does "remember" the last setting you used for the particular source equipment (e.g., the DVD/DVD-A player), though.
Mike, are you suggesting that optical cables often drop those 0s and 1s??? -- something I've never heard of, unless the cable is overtly defective. It is true though, that optical cables tend to be more easily damaged mechanically as compared with coax coppers.
