I have run across this in the past, and when I look closer, i find that I have a “hidden'” button somewhere (that you cant see) that is set to button number 1 (The default button) When you simulate from within DVDSP you click on your real button with a mouse (And it plays the target video assigned to it) but when you play the dvd in a set top player and hit play on the remote it is defaulted to the un-seeable, un-assigned button so nothing happens.
Take a very close look at you menu in DVDSP and see if you can find the mystery button. You will need to select everything in the menu and you should be able to see it. Delete the hidden button if you can find it, and your real button will then become the default button in your menu.
If you can’t find / see a hidden button then make sure that any assets you put on our menu (like a video insert, picture, graphic, plain text or whatever, are NOT set up as a button. All of these assets have the capability of being set up as a button, so it could be that one of these assets is your mystery button with no “play target” assigned to them and you would end up with the same problem.
Hope this helps…
