Dunno, since such svcds are mainly for standalone-players. I don't have one, and for my vdr-machine mpeg4/ogm is more interesting. I surfed around yesterday:

maybe this is interesting for you: ftp://ftp.vcdimager.org/pub/vcdimager/contribs - the package svcd-subtitles.tar.gz seems to provide some information on svcd-subtitles.

In the forum of doom9.org was also a discussion about this. It seems there are 2 types of subtitles. first there are the CVD-type subtitles as I-author does. About CVD Specs there is a article at vcdhelp.com (mainly as I remember 352x576/520 , mpeg2, playable too on some only vcd-able standalone-dvds) The second sort of subtitles are the OGT-subs, these seems to be the standard ones and there seems to be the tool winsubmux, that is able to do that, and the above package(svcd-subtitles.tar.gz) seems to produce OGT-subs.

As I understood the subs are muxed into the mpeg-stream, so mplex should do this. On vcdimager.org and vcdhelp.com are too some samples of svcd with subs. Since I'm not a developer all I can do is to provide infos I find on the net. Hope this is helpful. Too I fear this isn't the right list to discuss all this. Dunno about mplayer-abilities to play svcds with switchable subs …
