Strange...I actually haven't had any problems with the MotionPlus and EA Sports Active. The game doesn't recognize the enhanced sensitivity, of course, but the workouts all seem fine to me...
BTW, this site gives a rundown of different games that can be used for exercising on the Wii (it's got some good information on Nutrisystem too).

There's always debate of whether to go with EA Sports Active or Wii Fit or Gold's Gym Cardio or whatnot. To be honest, I started out with Wii Fit and got bored with it, moved on to Gold's Gym Cardio and got bored of that...today, I have all of them and mix them up
EA Sports Active is best for a good old-fashioned cardio full-body workout, Wii Fit is good for those days when you want to unwind, and Gold's Gym Cardio is the best for upper body workout.
