Hi, I have the following setup: Hitachi 57S715 Denon AVR-3300 Enery Take 5 Series speakers and sub-woofer. Panasonic DVD-F86 DVD player. I recenlt bought Panasonic DVD-F86 (for progressive scan). This DVD player only has Coaxial out. When connected via Coaxial to the Denon receiver -- there is no output in the sub-woofer. If I connect my old DVD player that has Optical out, sub-woofer works fine. Any clues? Thanks, Ravi.
