I GOOOOOT IIIIIIIIT!!!!!!!!! I bought the mac pro 12 core back in Dec. and it’s been not stop debugging. I think apple should work out the kinks before putting this stuff out on the market. So the issue of not being able to get the DSR 1500A to work with fire wire with FCP 7. You have to have the remote cable hooked up to the back of the Deck and the fire wire cable hooked up as well. I hope this helps.
