Hi there, I am very new at this. I am trying to capture video from my JVC mini dv camera using dvd santa. after a few minutes, my computer shuts down without warning. i have tried using roxio and windows and the same thing is happening. i have tried to capture from the camera directly and I have also tried saving the videos on my computer and burning them from there but the computer keeps shutting down. i am running vista on a new computer.
