When I try to import video into my computer, about five to ten minutes into the import my computer freezes and the import software I am using goes to ''not responding''. I started with movie maker and then tried a number of free internet downloads that are for DV capture. I am worried that my computer does not have the power to handle the video stream. Can anyone help or shed some light on this issue.
