Okay, I think I understand now. If I used the 5.1 outputs on the Sony DVD player straight to the amp I would lose not only the previoulsy mentioned sound managment features, but I would also lose volume control. I think that last one is the kicker. Having spent my last penny on this combo, is there anything (I'm trying really hard to be creative!) I can to do to avoid having to just sit and look at my new amp for two months???
