Does anyone use the IO box with a MPB? How do you have your drives set up? AJA claims that you can't use a FW drive at the same time - Because the box uses the FW bus bandwidth "extensively" - But that was back in 2004, so I was wondering if the FW bus has changes significantly since then and if you can use FW drives with the AJA. If not, do you use SATA? Thanks in advance for your insight!
