I use a Sony DCR VX2000 to shoot my videos. This camera is a DV tape camera but the way I've been using it is to capture the video by connecting iMovie (on my MacPro), to the camera with a firewire. Then shoot the video. I do not use the DV tapes. I can watch the video on my Mac Pro as it's being recorded. The video file is immediately transferred to my mac and I can play or edit in iMovie.
Yesterday while working this process iMovie crashed several times. Then it took forever to re start.
