What if we don’t want fancy features?

I’m familiar with some of the additional audio feature, like 7-1 surround and audio mixing where you can mix the audio from the main movie with your PIP. But, since I don’t want PIP when watching a rented movie, and am very happy with 5-1 surround sound, what “audio options” are we talking about? Yes, AQ is important, but what does 1.1 or 2.0 do to improve the AQ of a rented movie in 5-1 surround?

Basically I’m looking for a reason to get the better unit, but the only reasons I can find on any of the forums have to do with features that go way beyond just watching a rented move in the best possible Audio and Video quality. It seems as if all of the Profiles give you the best possible Audio and Video quality when just watching a movie. The higher Profiles just seem to add features for doing other things? Am I wrong with this?
