Howdy, I realize this is an old post, so I might start a new thread, but I’ve experienced the same problem a couple times – you have deck control but no video during capture – and each time the following resolved it.
I just quit FCP, turned off our Sony DVCam deck, waited a couple seconds, turned it back on, and opened FCP. This fixed it, so evidently something gets off on the deck’s firewire bus or the computer’s.
Has anyone else experienced a similar problem with the deck?
I have also tried quiting and “FCP Rescueing” (using the FCP Rescue software) FCP and when it came back up, it was experiencing the same problem during capture – deck control but no picture. The only thing that fixed it was rebooting the deck.
