Alright so Windows Movie Maker is really pissing me off. Lately, everytime I import a video, it chops it up into clips. Is there any reason for this?

Also, I've been trying to import this video, about 17 minutes long, and not only does it chop it up in to 10 second long clips, it's only importing about a minute of the video. wtf? Help fixing this would be greatly appreciated =(
I've had the same thing happen to me. I think it's supposed to make it easier to work with, being in sections.
