Was going to buy a sony vx-2100 and read on another forum that the professional new model ofessentally the same camera (the PD-170) has had production halted by Sony till they can get a fix on the audio hiss problem that occurs with the LCD monitor being used during filming. Anyone have a VX-2100 with any of these problems?? Was going to put in my order with B&H till I saw this today. JOHN
