Just discovered an interesting little bug after having installed Build 21.4.1. It involves the Mic level on Ch. 2. Get to it by going Video-->(AV Menu)--> Audio--->Ch. 2 switch to Mic. Select it to activate the adjustment tab. Rather than getting a dB level that can be adjusted with the joystick, it will be "locked" into: NaNdb which means I don't know what....

Anyone else seeing this?
