The more video you have on your card, the longer it takes for iMovie 08 to recognize the camera. If you have, say, 4 GB of data on your card, it may take 30 seconds for the camera to "appear" to be recognized. It actually is recognized immediately and iMovie 08 is working in the background. But, for whatever reason the Apple engineers decided, the user only gets a message that the camera is connected more towards the end of the thumbnail process than at the beginning. So, it's likely your camera IS recognized, you're just not waiting long enough. Connect it, and force yourself to wait. It's not like with a tape camera that shows recognition suddenly. It's working as fast as tape, you are just not getting the connected message until iMovie 08 looks at ALL your clips on your camera. Patience.
