"Double" subtitles

[Grossmeister]

I have DVD with 3 subs: English (IDs: 0x20, 0x23), French (IDs: 0x21, 0x24), Spanish (IDs: 0x22, 0x24), so when I demux this DVD I receive 6 .sub files.
When I open this DVD with DVDSubEdit, it says that subs 0x20-0x22 are "wide" and 0x23-0x25 are "letterbox". Also, movie can be played in 2 modes: 16:9 and letterboxed (with black strips up and down), so as I understand each sub's language has 2 variants for different movie scale.

Now, I want to remove French and Spanish subs, and also I want to add Russian. But I can't understand how to author DVD with the same "double" subs structure. How can I do it?

P.S. For demux I use PgcDemux, for authoring - muxman.

While authoring the DVD, the authoring app usually has an option to assign two subtitle streams per language. So you can keep English wide and English letterbox. Your DVD player will display the correct subtitle based on how you have configured your video. To remove the French and Spanish subtitles, use VobSubStrip (http://www.free-codecs.com/download_soft.php?d=2607&s=403).

Thanks a lot! I think previuosly when I tried to author DVD I made some stupid error. Now I authored using muxman and marked English wide (0x20) as wide and English letterbox (0x23) as letterbox. And I received DVD with double English subtitles (0x20 and 0x21) :) .

Now I have one more question: as I understand I need to create 2 .sub files from Russian .srt - wide and letterbox. I use SubtitleCreator for this purpose, and, I think, by default it creates letterbox subtitles. What should I do to create wide subtitles? Just select "16x9" profile or maybe I have to do some manual job to specify exact subtitle position?
