I need help finding the DVD-RAM discs and caddy for Hitachi DZ MV230A DVD camcorder. I can't seem to find the right type. I know that it has to be 8cm, and the disc has to either already be in, or go into a caddy. The owner's manual says to use DVD-RAM Ver. 2.1 or DVD-R Ver 2.0. I also need the stupid caddy as well. Any thoughts, I'd love to hear them.
