Just looking at my Canon HV40 tape camcorder. It has an HDMI Out on it. Maybe it's possible to connect the camera that way? Dunno. I've never done that; always with the FireWire.
Obvious option is give deck/camera to a friend who has a computer with FireWire. Since you'll be backing up to an external harddrive anyway (right?
), drop off the harddrive, deck/camera & tapes. Or do it yourself there, and have friend make you a sammich each hour. Good friend.
Oh, make sure the external drive has a USB port on it... so you can plug it into your laptop afterwards.
