I have a Dolby Digital DirecTV receiver which is connected to a Dolby Digital Stereo Receiver with an Optical cable. I also have a DVD Recorder that is connected through the Stereo Receiver with an optical cable. My question is this: If I want to record a program thats broadcasted in dolby digital onto my DVD Recorder and retain the digital sound, Is it enough to have this kind of connection or do I need to connect the DirecTV receiver to the DVD Recorder as well??? Please help. Thanks.
