yep, I did that the same day I unboxed it.
I only use the dynamic volume at night late if the kids are in bed, and even at that I use the day or evening modes to limit the dynamic range, haven't used the midnight mode.
for movies I normally use MultEQ with Dynamic EQ turned on. I guess I will have to experiment, but so far I'm pretty impressed when I compare Audyssey everything off to on. yes, I have the feature upgrade.
I will say the overall sound for music and movies seems to be better than with Audyssey off.
