How would one go about converting those discrete codes into hex for use with the RM-AX4000, provided that's possible? I used to use the DVD analog audio input for watching tapes or TV and the Video 2 optical input for watching DVDs, but I recently a coxial cable for the DVD player as my receiver has a digital coax port for the DVD input so that I could use the Video 2 optical input for the Squeezebox. The problem being that even if the DVD player isn't playing, it still gives a signal so that the receiver (input mode on auto) plays the coax sound (or lack thereof) and never the analog. Of course, Sony didn't apparently find it important enough to put an input mode button on the original remote. Thanks in advance for any help.
