It works here with xv/x11 (nvidia card).

It displays the nav menu but there are a few glitches (as you may expect
it for an early alpha ;), that's not bugreports just an enum FYI:
 - the choice is not displayed/selected (as in ogle for instance where
   the chosen menu is of another color)
 - -cache messes the navigation keys (they don't seem to work any longer)
   and without -cache playback is bad quality
 - seek does not work as it used to (with plain dvdread support I mean)
 - the movies don't seem to start on the DVD I tested

Anyway, it looks quite promising :)
