modify subtitles info

[max0069]

Hello! (...excuse for my bad english...)

I want to know if is possible to modify
subtitles info in the IFO files (...fonts and/or fadein and fadeout).
Example:
Many subtitles have a different font type
and/or have a different fadein/fadeout time.
Is possible to modify these info in the IFO files? ...How?

HELP!

No. Effects are defined in subpicture "spu" packs. Look here. (http://dvd.sourceforge.net/spu_notes)
Subpictures are bitmaps, so you cannot change fonts.
