Hi all. I have a JVC GR DVL357. I was wanting to back up some old tapes onto DVD or the pc. Now, I used to use firewire on my old pc. My new pc gigabyte z77x d3h doesnt support firewire. so my options appear to be as follows- buy a pci firewire card. Or can I buy a usb3 cable that will transmit data fast enough to record/convert? Normal usb2 is only good enough for still images. Any ideas? cheers.
