You are viewing OTA content, which is mostly (99%) 2.0 content and not 5.1, so the improvement in sound doesn't amount to much via the digital optical connection in your case. In this regard, I would suggest you continue to use what works since there clearly is some sort of conflict with your equipment preventing the Denon from working properly, or the HDTV simply does not work as it should via digital optical out in back. Boost the sound quality a little by utilizing the 'faux' dolby settings on the receiver.
