Audyssey also adds another element of user error that is hard to diagnose along with other user setup problems like placement, room, connections, calibration, receiver settings etc that can be tough to determine over the phone. From a customer service standpoint you have to isolate variables. It wouldn't surprise me if they get a ton of calls about auto correction programs causing problems/user error. It only makes sense that the manufacturer would not recommend auddyssey or tell you to turn it off.
