Debbie's right, and I think also if you click on the name of the DVD on the bottom left corner of the home page, it will bring up the chapters and their numbers so you can pre-program more easily. I have found that I never use the programming method, because it is just so easy to flup around with your skip button, or by going back to the main menu or mix and match menu (depending on the DVD).
Have fun with them!!
