I have a 7.1 set-up (from a speaker point of view) but something has occurred to me recently. In the old days of PL (and thus I also presume PLII) the rear speakers were exactly that. Namely at the rear. With the advent of DD the effects speakers are now positioned on the side walls. In PL mode do the amps now send the effects channels to the correct speakers at the rear or does it compromise to accomodate both formats and just send them to the side?
