I found my copy of The Hunt For Red October, and have checked it out.
You won't like my answer, however.
'The Hunt' had 3 substreams listed: 1.) English, 2.) Spanish, 3.) Undefined.
Undefined turned out to be the French subtitles, all of which display throughout the film.
The short answer is that what you want to do can't be done.
There is either another mechanism at work, or there is something in the DVD specs that allow this to be done, and it's not being checked for by any copying program I have. They all report the normal audio, video and subtitle substreams, but to pick off this option requires something extra to be found and reported and utilized by the copying program.
Maybe a good candidate for the 'Added Features' list?!!?
