please help !!!

I have a JVC GZ-MG27 20gig digital camcorder. With it I purchased the JVC CU-VD10 share station. It is a direct to dvd burner. The directions say to turn the power off on both items connect them both with thier power supplies, then the usb cable from the dvd burner to the camera. turn them on, select the video to burn. the screen says insert disc. after doing that the screen says recognizing disc. then says incompatible disc. JVC tech support says to make sure I am using dvd-r disc's. I have tried sony and the jvc disc that came with the burner. still no luck. I bought a second dvd share station and it does the exact same thing.
