I have the same Sony model DVD jukebox. You can select a disk in another way. I am at work so I go by memory here. First, with the switch on the remote set to "DVD" you hit "display" and at the top you see the current disc number. Hit "enter" and this number goes away, then type in the number of the disc you want, and hit "enter" again. The disk will play. You then have to hit "display" again to turn off that menu. I used this sequence of buttons to program my harmony 659 remote.
