Buggy menu

now, that I finished my course for a Video DVD that works, I could try it in a 
true DVD player. It mostly works, except some menus :

- a simple two button menu : I cannot change the selection

- a three button menu : it goes directly from 1 to 3, and 3 to 1. No stop on 
the second one.

All this menus work well with :
- xine dvd://
- vlc dvd://

and even a WinDVD I could try. So the final question : is there some way to 
create run everywhere menus? Or anyone knows a validator?

Thanks
