I went to the Apple Store for an answer and I didn't get one.
A client with a Mac wants to make a DVD from an iPhoto slideshow. The DVD is for a 50th reunion, and she wants to distribute a disk to each attendee. Given the age of attendees, handing out flash drives or giving them a link isn't going to cut it.
iDVD is no longer available. I don't know how to create a DVD playable on a standard DVD player.
