I have a Onkyo TX SV 373 reciever, Sony SLV N50 VCR hooked up to a Sony Wega TV. Paradyme Titans with subwoofer, Bose center channel speaker with 2 no name speakers in the back round out the system. When I hit test on the reciever it sends white noise to all channels so I am fairly sure everything is hooked up correctly. However. while a movie is playing on the VCR I get no sound from either of the rear speakers. I've tried various settings on the reciever but have yet to get the rear channels to work. The sound up front works, just nothing from the back. Any suggestions or help is appreciated.
