when video editing, have at least 2 hard drives. one for windows and all the programs, then another one for the video files. this way, you wont drop frames and audio for stuff that accessing the main drive. if you want get a 3rd drive. when you goto render your movie into a dvd or somethen, you can save it to that drive. This will really speed the render the process. You have the one drive just reading and feeding the other drive. What version of pinnalce studio are you using?
