Studio 11 do not accept the USB cable which was with the camera.
DV Tape Cam Manufacturers don't usually supply a "Firewire" (DV transfer) cable, only a USB cable, for downloading Stills (not video), to your PC. You need to buy one, if you haven't already got one from your old Cam, which is also a DV Tape Cam.
