I have a samsung DS610 I also have a phillips tivo direct TV DVR. My phillips has a digital output, my samsung has two digital inputs. I have a monster cable digital cable. Once connected I change my samsung input to digital 1 (where I have my phillips output plugged into) it searches for a siganl then stops and no sound is played. I have a signal (I believe) comming from my phillips (red light at end of cable). I have tried both digital inputs on the samsung with the same results. I am frustrated and could use some advice. Thanks in advance, J.
