I use the Alpine skin for MediaCar... every so often if i hit the MUTE button I am hittin gthe LIST button... ie. in windows, if i want to hit the start button the cursor may be a half inch to the left or right or up or down or something from where i am pressing... i then have to do a 4 or 25 pt calibration... but is there a reason it keeps going out of calibration? Also whats with all the "threshold" settings in the driver software?
