Why is there a need to mix stuff in 7.1 when it was never intended for it? I'm still not really a fan because I've always felt there should be a rear center plus on old roadshow epics like Spartacus the surround was mono only and at the time would have been largely limited at best. I can understand losing the two front channels because there's no modern equivalent way to play them back. what always gets lost though is all the directional dialogue effects and panning which is ridiculous. And of course nutty me would wish they'd include the mono mix just for comparisons sake.
