I am going to order a JVC HM-DH40000U to archive some programs from my Motorola 6412 in HD. I want to order the correct firewire cable to connect the two devices. I can't seem to find the correct firewire cable to order for this connection. The so-called expert help line on Vanns was no help. Has anyone done this? Should the cable be 4-pin to 6-pin or 6-pin to 6-pin or what? Any help the group can give will be greatly appreciated.
