I am currently viewing digital TV via a Humax pvr 8000T connceted to a Denon 1905 by optical for audio. I have the Denon set on Prologic2 so enjoy stereo sources reproduced into 5.1. My question being having recorded any TV on the Humax and played back I seem to lose the sound in the Surround (rear) speakers. Is this normal, or do I need to alter any menu settings? Would appreciate any help, Thanks Andy.
