Are DVD menus undetectable??

Hi all,

I'm currently looking into a way to detect the presence of interactive DVD
content, eg menus, in order to automatically launch appropriate controls
(like xine-ui's DVD navigator window).
Currently, xine doesn't provide any interface for that, probably because
for dvdnav, there is no real difference between just video or an
(animated) menu...

However, it may be possible to detect the presence of a sensitive area on
the screen, no?

Any ideas?

Cheers,
        Siggi
