When googling, I've found a very good freeware program (called Gilraen)
not HoMM V related, but created in the HoMM V style !
Even without this style, it's good,
but with this style it's excellent !
(you, fans, understand me )

It can bring a LOT of cool styles to your subtitles
to enlarge the pleasure from the movie
(subtitles are very helpful
when learning the new language)
