Export Imovies to Dv Tape


I have iMovie 4. I'm using OS 10.3.9 on aa G-5 dual processer.

I have a 14 min. iMovie. Every time I try to export it, I get the message "Lost Connection to Videocamera." I have tried plugging it into the firewire connection both back and front, but it makes no difference. I have tried using a Pyro A-V link to export directly to videotape. I get the same error message. Can you help? Please??
