I have a JVC HR-S3600U SVHS VCR with the ususal RCA type audio/video (red, white yellow) cable into a Denon AVR-3300 receiver. I also have a Toshiba SD-5109 hooked into the receiver via a coaxial digital cable. The Dolby digital is fine. My problem is that I can't get surround sound from the VCR to the receiver either from cable TV ( I use the VCR as a tuner), or from movie tapes. I get theses fine in another room hooked similarly with different equipment, ( not quite as high end, just works better). I think I've tried every permutation, even read the manuals in a burst of desperation. Any ideas?
