Ive had my dvx100a for a while now and have always had problems with the audio. My friend has a VX2000 and a lot of the time we shoot things at the same time. His footy always has much better audio. some cases you can hear full conversations with his and cant even hear noise with mine. i havent really played around with the audio functions but is there anything i can adjust so it picks up more sound? (besides getting an external mic)
