Boldstrummer, that created a bit of confussion for me as well. My unit has one set of l/r outs and one set of 5.1 outs. The stereo outs output the same signal as the mains of the 5.1 set of outs. Since I don't have rear amps at this time I am running he-rez in two channel mode and I use the l/r outs to my sub.
The remote is a solid YBA remote. It offeres fine adjustment of the volume, source select, power, mute and other YBA/AR components.
