I wouldn't use a football game as an indicator of correct surround. If the surrounds are too high try trimming the levels a bit (and you could use a memory function to just use it for certain type of content). Why use Dyn Volume? Does your model of avr have the the dialog enhancer option? Volume level of 35-45 seems very low (on the relative scale I have my gear start up at a low volume of -40, which is about middle of your range....but I don't find that particularly listenable, just don't want it too loud on start up).
