How do you connect the Cam ? For video you will probably need to use a firewire cable and open iMovie while for Photos could be better the USB and iPhoto.
Unfortunately I do not know the Camcorder enought. Have you tried to take the SD card and read it in the Mac ?
You will probably need to follow the folders to reach the video streaming. May be you have folders like Private... AVCHD and under them the video files.
Can you post here how is the folders and files names ?
I have a Sony AX2000 HD camcorder and use USB to connect the camera to the computer, then when the icon appears on the desktop, open it and browse to the AVCHD folder and drag the whole folder to a folder to the computer. When it is copied, you can eject the icon and disconnect the camera. Then, Import the separate MTS files in the AVCHD -> BDMV-> STREAM -> folder to an editor or video converter to get them into .mov files.
However, I am having problems with any converter getting good results from MTS to .mov without adding frames, or showing ripples throughout the video on DVD. Premiere Pro CS4 handles the MTS files great, but getting them into a format deliverable to DVD is my current headache.
