Ogle can't read any data.
Make sure that the CSS authentication works correctly.
See also the FAQ at http://www.dtek.chalmers.se/~dvd/faq.shtml
Three common problems are:
no write permission on you DVD drives device node.
you are trying to play a DVD from a region other than the one 
of the DVD drive.
or you have never set the region on the drive.

For setting the region; a program called regionset will do this.
Search for dvd_disc or dvdkit on freshmeat.net
Beware that you can only sset the region 5 times!
