I want you remove parts of a video movie that I recorded while I was kayaking down the Kern River.  There is a bunch of dead time that I want to cut out of the video but as far as I tell, there is no option to do this inside Windows Live Movie Maker.  All that is provided is a trim function that allows you to setup a start and finish time and only trims from the outside of the video and not the inside.  Any Ideas as to why you cannot cut, remove and/or delete parts of a video using Windows Live Movie Maker?

An example:  I want to keep the beginning of the video all the way through to about 15 minutes into the video at which point 15 minutes into the video is my starting point of what I want to remove from my video.  From this point I want to remove the next 16.5 minutes following the 15 minute mark of the video.

I have tried selecting the start of the 15 minutes after the video starts and selecting the 16.5 minutes afterwards but ll that happens is that everything from the start of the video and inward to the 15 minute mark of the video gets deleted and the same holds true for everything from the 16.5 minutes following the 15 minute mark all the way to the end of the video gets deleted too. 

It should be the opposite.  Any help would be greatly appreciated.
