maybe the disc is encrypted.
can you copy the disc content to harddrive?
it is better to play it from there, and to be sure that it is not a
corrupted media.
after copied, try play it using libdvdcss builted in mplayer. try this:
mplayer dvd://1 -dvd-device /path/to/copied/content

btw, this is ffmpeg user mailing list, not mplayer, in case you choose the
wrong address
