I have found that the best way to pass audio from my cable box is to go RCA left/right from the cable box to the VCR to the TV in. I have added a home theater receiver to the mix. If I go RCA Cable Box out>VCR audio in>VCR audio out>Receiver audio in>Receiver audio out>TV audio in will I get TV programs that are recorded in Dolby to come out in Dolby on the receiver and still have use of the TV speakers? Any drawbacks to this config?
