I've found a better way. For DVD there are also CC-subtitles. Nearly all
RC1-DVDs use it for english subtitles. And CC is a 7-bit-like charset -
also a 386 could handle them.

See CC-FAQ at http://www.robson.org/capfaq/index.html

I don't know, yet, if it also can display graphic, but it would enable
embedding a ASCII-based OSD in MPEG-stream.
