Being slow as usual, or maybe even slower this time, I may be mistaken, but
we're talking about converting the bitmaps/IFO which are extracted from the
DVD with -vobsubout etc to *text* with some kind of OCR tool? If not, then I
still don't understand... *pok* :( I never got around to putting the bitmaps
subs on-screen. I tried, but mplayer kept complaining they were not in a
recognizable format. Does mplayer take options for viewing bitmap subs, as
extracted with mencoder, using the proper IFO? Is this (original?) subtitle
format widely recognized by other players (ie filter plugins)?

I know, I was only using an example... Extracting the DVD movie, the DVD
audio and the DVD subtitle are fundamentally the same thing to me. But thats
just my view on the task at hand, where the method is just as important as
the result, if not more important. The dude that made the downloadable
subtitle -propably- also made a rip, which can be downloaded. Somewhere.
Somehow. I admit, I have downloaded subtitles, but thats due to the blatant
incompetence I'm demonstrating here, claiming the bitmap subtitles to be
garbage... thehehe

I ofcourse acknowledge the fact that OCR is a complicated image pattern
recognition challenge, and that most OCR systems are somewhat fragile.
