Thank you you guys, specially Zane, you are right,
shouldt let the technical problems hold me.
but I am in HongKong and this expresscard I bought for year ago.
I got a job and it’s urgent to finish so I cant choose other solution!
I have remove my mbps firewire config in the network, and let Final Cut Pro rescan the device,
still fail. I think there must be some problems about my card or DV.
