I had this feature enabled before, in a cvs build,
think it was 4-7-2003(its suposed to have support for it non the less)

its some kind of tagg, like <dvdnavigation>true</dvdnavigation>
or something..

Anyone remember?
the cvs build is still available at #xbins.

If I remember correctly, the tag itself didn't do anything.. I.e. it made no difference if enabled or not. From what I understand, the dvd menu/navagation system is still being worked on.. Therefore, it doesn't really mater what the menu says since the option does not exist as of yet... Someone correct me if I am wrong.
