I am trying to add video created by a groom and given to me on DVD into the wedding video that I shot. I cannot figure out how to do this. Can someone please help me?????

In edit mode click on the "File" pulldown menu and a little over halfway down you'll see an item "import DVD titles".

It worked the one time I tried it, but this will not work on commercial copyright and protected disks. Should work from the disk you were given.

Good luck.
