Thanks for your reply. I believe I have set the video preference correctly, because it used to work on my old machine which had Win XP Home.
I’m almost certain the problem is related to Win XP SP2 because I had same problem with AVID Xpress Pro HD, and the problem was simply solved by manually registering one of Avid’s DLL files. I hope someone could tell me which DLL file in After Effects is responsible for managing the firewire port.
Thanks again,
