Once I stalled the Comcast DVR, I could no longer record DVD's from television(cable.) My DVD Recorder (outputs) is hooked to my TV (inputs)with RCA cables. I used S-video to connect the DVR (output) to the DVD (input). When I got ready to record from a TV program I used my DVR remote to set the source to S-Video. It recorded the picture just fine, however, no sound. HOW CAN I GET THE AUDIO?
