Drop down menu animation

i was wondering if it would be better to use an xml drop down menu versus just a flash menu… would the animation be smoother… i used the tutorial here for a drop down menu and placed it within my movie… and the button’s are very inconsistent… one minute they will drop down and then roll up- the next minute they’ll drop down and remain… the movement to me look’s very choppy at time’s… plz advse…
