Hi, seems I’ve got the bug too! Got 4.5 HD on my Powerbook 800mhz/512mb. I work in PAL format. Been editing happily for years. Just finished project and deleted all capture material on ext. WD firewire drive. Launched FCP and got message saying: “Unable to locate the following external device: Apple Firewire Pal (720 x 576) Your systems config may have changed, or your deck/camera may be disconnected or turned off. Please check your connections and click “Check Again”, or click “Continue” to set external device selection to None.” I’ve deleted prefs, etc, I’ve tried connecting camera directly to int. HD, been thru disk utility repairs. I’ve noticed when I choose “Continue” my FCP takes a VERY long time to open and my Firewire HD is working to the max, something screwy there! Cannot log and capture. Help? Deadline!
