Preferably I would recommend an SPL meter for calibrating your speakers. As for Audyssey EQ I would recommend you turning it off initially to eliminate as many variables as possible as to what could contribute to dialogue problems. If you decide to re-calibrate with an SPL meter try some listening with both auddyssey turned on and off and see which setting you like better.

Another thing to check is to make sure all drivers are working properly on your VP150.
