I bought this little handycam which has an SD card and came with a USB wire. When I tried to import video into iMovie via the USB, nothing appeared to happen. I tried opening it in Quicktime as well - nada. My son was able to edit a short movie on a friend's PC which has an SD slot. But I'd hate to think this handycam won't let me edit stuff on my Mac. I'm not a techy kind of person, but I have a Firewire - can I do a USB to firewire connection somehow and would that help? Will I need to buy an external hard drive?
