The default Microsoft one is the only one that I test against. I found the Cyberlink or Intervideo ones can behave incorrectly in a few places (mouse clicks, not showing which menu item was highlighted etc). They're supposed to behave the same way as the Microsoft one, as per the Directshow IDvdNavigator standard, but I guess there is small differences in the implementation of each.
