You can see subpicture streams in SubRip (http://zuggy.wz.cz/dvd.php). Open your titleset's .IFO (or a .VOB,) select the stream you wish to view, choose "Only Show SubPictures" action, and click Start.

Look if that code is useful for you.

Using this, you can at least parse the sub-streams incl. their language codes.

But I do think switching on/off them needs a deeper structure patching which isn't only done by patching the IFO files? Well just check it out.

Use Pgcedit - doubleclick on title - in Pgceditor disable the specific subtitlestream
