I have been enjoying my new JVC 3000, with my Panasonic 3000.. I am using the proper PK-EM2 emitter.One of my glasses stopped working and I need to replace it. The book says to replace it with the PK-AG3 glasses. I see some advertise the AG3P glasses, while most advertise the AG3G. Is there a difference? Should I be concerned?And do you know a good dealer to buy the glasses from?And while I am here is there anyway to make the picture a bit brighter? Just for the 3D. I have these controls on on the Panasonic
