My Sony Viao computer came pre- packaged with a sony program "Click to DVD"  I'm not sure it is available as stand alone.  It is a less sophisticated program than what Bryster is describing.  I have used it to create slide shows of digital photos set to music.  Creation of title screen is included but any additional credit screens  would have to be created by you as an included image.  It also can be sync'ed to music included or from your personal files.  Finished product is self starting DVD. Perhaps you can google it. 

It can also create and edit dvd from digital and analog video.
