Just realized that all the firewire ports on my 8-Core mac pro share the same bus. I need to capture video from a HDV camera to a firewire hard drives and I get hickups and slow downs that cause dropped frames. Can anybody share any links to what FW card to get to and where I can buy it from? Anything that does not cost to much? Please only post links of cards you have used or read good reviews using it on a Mac Pro. Also what slot would I put the card in? I want to make sure the slot is not also sharing a bus with something else.
