      Applications can not access to the latter part of large file (over 4G) when it is mounted with mount_ntfs. 
      Prepare an ISO file which contains a movie (over 6G). Put it onto a ntfs (created by WindowsXP) and mount it with mount_ntfs. "Mplayer -dvd-device /$MNT/movie.ISO dvd://1" should play whole of the movie, but it stops about 2/3 of the movie. 

      This is not a mplayer's problem because mplayer can play the same file when it is on the network (and mounted with mount_smbfs).
