Connecting my BD-80 via 5.1 analogue output, to my Denon amps analogue inputs (my amp doesn't process HD audio). Sound options in BD-80 menus give choice of Bitstream or PCM. Which do i choose ? I've read on forums that Lossless PCM is what i should be using but that's not an option i have, or is PCM on the BD-80 the same thing ? Thanks in advance for any advise.
