here are the basics: Macbook OS 10.6.6 imovie '11 9.0.2. Canon Vixia HF200 Card: 8GB Speed Class 4 The HF200 is and always has been recognized easily. When I bring up "import from Camera" it shows me all of the clips on the camera and I can click and choose which clips to bring in. Sometimes it will import the full clip, but most often it says there is an error and it imports only a portion of the clip. There is a higher success rate with clips under 5:00 in length. I have re-initialized, I have re-booted, I have used other USB cords and ports. I never had this problem on my PC. However, I could never import to movie maker as I had to go through Pixelia Imagemaker or something like that. Do I need some sort of similar program for the mac? I was told I dont need anything for imovie. I am getting sooo frustrated and I have called Tech Support from Canon and Mac and neither could solve it.
