The 5 speakers are in the ITU configuration(?) but I suspect it might be better (and extremely costly) to add two sidefill speakers and/or rear center(s) for movie soundtracks.

Guess I also need to look at the spec requirements for 5.1 and 7.1 soundtracks. What forces the player/receiver to "fold" 7.1 into 5.1? This seems a fairly nontrivial task for PCM, TrueHD and DTS HD MA soundtracks.

"What forces the player/receiver to "fold" 7.1 into 5.1?"

Simply the fact that you tell the receiver you have a 5.1 system rather than a 7.1 system. It's already doing similar sorts of things if you tell it you don't have a centre speaker or if it's a 5.1 soundtrack and you've told it you have a 6.1 or 7.1 system. I suspect all that gets done to fold 7.1 to 5.1 is that the rear surround info is added to the side surround channel on that side.
