Can anyone tell me how to copy DVD from a PC or DVD player back to a DV tape via a Panasonic NVGS 400 Camera. Why would anyone want to do that? I have a sports program that requires a DV Camera input to operate & want to utilize existing DVDs for training. Can copy from camera to camera via firewire which doesn't help here, but have tried the camera with the start & record buttons pressed together in both VCR & camera mode playing DVD via my PC's 1394 port but it does not appear to send an output. Is 1394 firewire supposed to be bi directional. Any hints would be appreciated.
