I'm like getting this message. I'm using a firewire though, and everything is plugged in right. I've used it before, only a few times though, and last time was a couple of months ago so memory is foggy (champagne not helping. Happy new year!).
I'm plugging in my camera before starting Premire. Camera is plugged into it's power. I tried both camera mode and play mode. Then I go to File/Capture/Movie Capture. Both the sound and video buttons are pushed down. My settings under the edit buttons are fine, the ones I've used before. I've even tried playing the movie before I try capturing, since I've had luck with that in the past with different software. I can't figure out what I'm doing differently! This is my husband's birthday, my son's birthday, and Christmas on this tape and if I can't get them on dvd I will cry for weeks. GRRRR!!!
