Ours did that too. We chalked it up to crosstalk from the RS-232 communication to the servo PWM inputs, as we have all the signals running through a multi-conductor cable up to the camera assembly. It was fun watching the camera "nod" to the beat of the music before a match.
Today we replaced the last bit of cable to the serial input of the camera in an attempt to track down an intermittent communication problem. It fixed the problem, and it also seems to have stopped the servo jittering at zero during disable.
