Another way is to find the movie PGC and directly before any commands that actually play the title (e.g. “Break”, Link Cell, Link PGN, Link PTT, etc) [B]and [/B]at the end of the precommands, enter your subtitle =0, off command.
This is very kludgy, but will work. Typically, if you want to see the subs, you’ll need to turn them on by the remote (although the language menu should work if a RSM is issued when you resume playback, as this will bypass the precommands). Also, you need to be aware of any streams that the authoring wants on by force (e.g. foreign language speak). Setting a register to 0 will turn these off, too. You don’t want that to happen in The Last Samurai or Dances With Wolves!!!
