I just bought my 27" iMac and I recently purchased a Canon HF200 HD camcorder also. The camcorder records to a SDHC card. The first time I loaded video to the iMac, I just put the SDHC card into the SD slot on the side of the computer and it worked fine. It imported into iMovie great. Now when I insert the SD card into the slot, it just pulls up iPhoto. Even if there is nothing to import. I have video I just shot on the camcorder on the card. I tried using the USB cable that came with the camcorder also. I can load it to other computers, so I know the camcorder is recording just fine. Does anyone have any pointers for me? I don't know where to start. Best Buy recommended me using a firewire connection, but I can't find a firewire connection on my camcorder.
