I have a Pioneer player that was issued in 94 or 95. It has a AC-3 RF output (that probably was added by the previous owner), but it doesn't have a regular digital output. Is that something you can add to it, or should I buy a new player? Also, if I were to buy a demodulator and connected it into the AC-3 output, would that operate as a digital output into my receiver? Or is the AC-3 output only set set to detect those signals?
