I am in the process of making a video and cannot get imovie to recognize my camera either. It has for years, but now it does not. I am using Imovie 6.03. I use a Sony DV (TVR900), with firewire. I have tried other suggestions on web (plugging, unplugging, rebooting, setting dates/clocks, etc.), but nothing seems to work. I have even tried other dv cameras. I do have Final Cut Express and it does work there. I am just not as familiar with it and need to make a quick video. I need some expertise help on what the glitch could be!
