I use a JVC GZ-MC500. It uses a 4gb microdrive (compact flash). My first try with imoveo8 was with the summer vacation shots, 220 files. Imovie08 recognizes the camera and produces grey previews and no sound is imported. The JVC stores each 99 files in a diferent folder, I deleted folders 2 and 3 and leave de folder one, with 40 files, then the import was perfect. Second thing I did, was leaving folder one complete with all the 99 files, and folder 2 with 40 files. Imovie08 didn´t recognize the camera.
I hope apple support take note of this and fix the number of files bigger than 99 issue in order to use our mpg files in our JVC cameras, now imovie08 is useless for me, I back to windows edition.
Best regards.
