You can add some video files to your DVD using the Timeline. To do that click the Import Video button on the Timeline Toolbar. The video will be added right after the previously imported video or to the beginning of the DVD if no other video has been imported.

Note: if you import a video file after some video has been loaded into AVS DVD Authoring, a new chapter will be automatically created and added to the beginning of the newly imported video.
