Please could someone tell me the answer to this question! I am going to buy an external hdd with 1 firewire port and 1 usb port. I want to use it for imovie, but i only have 1 firewire port on my iBook, and that will be used by the camera. So my question is, can i import the footage, and then transfer it to the external hdd, via usb, whilst in imovie? Sorry if its a bit unclear, but i just want to have space for big movies and not clog up my Mac HD.
