im no expert on this but,
check where you got from. if its a torrent then go back and read the gumff.
what i would do is use 'dvdshrink' (you can download it through torrent network), which is a dream of a piece of software, to check out how the file you've got is structured. it'll tell you about the languages menus etc. then burn an iso. image of it with imgtool or similar and then run it on daemon to see how its come out. then burn it.
if that fails. try another torrent
