DVD Studio Pro, Play button going to Scene selection

Hi, Something happening I haven't come across before. I've set Play button in main menu to the track and SceneSelection to go to first menu page. I've done this countless times.

But tested on two dvd players the Scene Selection button comes up as highlighted and if pressed goes directly into the movie. When Play is pressed this goes to the scene selection menu.

This doesn't happen on the Mac DVD desktop player although Scene Selection is highlighted first - other than that they are directed correctly. (Although I did notice that despite Remote Control settings correctly set - Title should send me to Play but goes to Scene Selection instead and vice versa)

Double checked everything in DVDSP and rebuilt DVD - no luck so far
