How do I play a local DVD copy in "DVD mode" using Xine and/or Mplayer?

"Assuming your dvd folder is /path/to/movie/VIDEO_TS, try

xine dvd:///path/to/movie/

or

vlc dvd:///path/to/movie/

mplayer plays the movie, but I couldn't get it to play it in DVD mode. Apparently, the packaged builds of mplayer don't quite have menu navigation support yet.

mplayer dvd:// -dvd-device '/path/to/movie'

If your build of mplayer has dvd menu support, you should be able to invoke it using dvdnav:// instead of dvd://"
