DLP color wheel rpm and segments.

They probably lowered the rotational speed to lessen the customer complaints
of whistling or buzzing noises being generated. Have replaced quite a number
of them already because of that specific complaint. Personally I would steer
clear of Samsung and go for the Hitachi. Their 50V500+ series are quite nice
items.
