I work for Apple Computer part time, If you had a Mac, it would be VERY easy, as all new Macs come with software called iMovie, in minutes you can be editing your video, add title, transistions between clips, 2 audio tracks if you want to add music and the models that have a Superdrive (DVD burning) the software on the computer to make your DVD's including chapters markers.
I'm constantly getting customers who come in that own PC's, who wanted to make DVD's with their PC's and cannot, I show them in 5 minutes how easy it is to work with a Mac, they can be up and running and know to to use the program that fast.
Someone I know who bought a Sony Vaio system to make videos of his new baby and gave up after 3 months and came in and bought a Mac .
