In the VidCap program, under Options / Preferences (either the general tab or the capture tab, i forget which) is an option to enable DV scene detection. You probably turned this off. Check it and you will get separate files for each scene.
ok, i think it was becuz the clock wasnt set in the camera since i had to reset it, but it will still capture stuff as 1 big scene that was recorded while the clock wasnt set right?
