Is the camcorder a digital cam? If so then you can easily (and cheaply

) capture the tapes to your PC via a firewire connection (do a search on here for more info on firewire).
Digital camcorders all have a DV-out port, but some also have DV-in enabled on the same port. You
need DV-in to be able to copy the edited video back onto the DV camcorder. Many camcorders sold in the UK however do not have DV-in, so you need to check the specs of your cam.
Mark.
ps, firewire aka iLink, ieee1394, DV port
