I'm using a Pinnacle DV300 capture card with a Panasonic NV-GX7B camera and Adobe Premier 5.1. I can capture and edit films with no problems, but when I attempt to send the film back to the camera using firewire and the DV-In port, I get the message 'Disk to DV upload Error'. The most I've managed to send back to the camera is 1 or 2 frames before the PC gives the above error. I've tried everything I can think of but I cannot transfer data back. Any ideas??
