Like Groucho said, the mini DV has a much better image quality. The mini DVD are great to just pop out of the camera and play on a DVD player and watch. Transferring the video to an editing also seems to be a little easier and quicker when using the mini DVD, but in my opinion it doesn't beat the difference in image quality of the mini DV. Also, most of the mini DV camera's I;ve handled seem to be a little smaller and a touch lighter IMO.
