Hence, You stumbled upon the trick I mention in my Previous post. I've been using this Trick for 2 Years now with my Mac Mini. My camcorder is not on Apple's recommended & compatible Mini DV Camcorder List. I can't take credit for the Trick. I found it on a Forum 2 Years ago. All you others who are having a Problem, Should Try this "Trick! The original fix is connect Camera to Mac. y. It works everytime for my Samsung.
*The Trick:iMovie Camcorder Import Fix*
*Connect your camera. put it in 'play' mode (sometimes also called vcr). start up imovie (hd or 08; both work, but i use HD). go to the blue 'import' screen. it should just say 'camera connected'.*
*Now comes the trick. don't click import, but instead put your camera in 'record' mode. you should now see whatever it is that your aiming the camera at on your computer screen.*
*QUICKLY put your camera back in play mode. again very quickly press the 'play' button, either on the imovie import screen or on your camera. your DV tape will start to play back.*
*-On my computer, the video now suddenly shows up in imovie! You can now click the 'import' button in imovie, and imovie will start importing the tape in realtime. This is a bit slower than the normal import method, but hey, at least you can now get your video into imovie!*
