i had the same problem with the STOP buttom of my PANASONIC VCR NV-HS 830. fortunatly i first get a older test remote from my hifi shop. after i told MARANTZ that i won´t buy this RC 3200 without all buttons are working. They said that i can buy a new one,because they changed a CHIPSET inside (Marantz Hotline Germany 07.Nov.2002).so i buy one today and it works properly. maybe the same thing with PRONTO NEO????
sorry about my english
