There are various versions of DVD MovieFactory.
For instance you will NOT be able to do the following with the version that ships with MediaStudio8.
The procedure with DVD MovieFactory Disc Creator is:
1. Start a new project.
2. Add Media.
3. Below the "Add Media" icons is a section "Add/Edit Chapter" and to the right of that are two downward pointing arrows. (Click)
4. Now Select "Multi Trim Video"
5. Use the "Start/End" buttons to mark various sections of the video you wish to keep. Each marked section will create a new thumbnail at the bottom of the screen.
6. Press OK to complete the process and return to the previous screen. If you now preview that video it should have cut out the unwanted portions.
If you want to do something more exotic like adding transitions between these trimmed clips you would find it easier with VideoStudio 9
