A couple years ago we bought the Hi-Rez DVD Criminally Insane. This year we wanted to add the flickering light triggered off the DVD via DTMF. Instead of buying the Hi-Rez decoder we got a generic one off eBay. They look virtually identical. Of course we can't seem to get it to work! Everything seems to be hooked up and running fine, but no interaction from the DTMF board. Is there a secret to getting it to work? Is the tone only for a certain relay on the board? Or is the DVD made to only interact with the Hi-Rez branded board?
