Maybe try 'mplayer -dumpstream -dumpfile FILENAME dvd://CHAPTERNUM', or the same with 'dvdnav://' if you can get that working? Or 'mencoder -oac copy -novideo -o FILENAME dvd://CHAPTERNUM', similarly, and possibly with an appropriate '-of' option if one is not selected automatically? (Per the man page, you may need '-vc null' instead of '-novideo', but I haven't seen that in practice.) I haven't done much with this sort of thing recently, but once upon a time those are the sorts of things I'd have tried. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
