Next time I'm in Japan, I plan to look for and buy a DVD for which I made fan subs.
If a DVD has subs, chances are the pirated versions of it contain the ripped version of those subs. Fansubbing generally refers to making subs for material that has no subs at all, or not in that language. OCR-ing some captions or subs and pumping through Google translate isn't exactly fansubbing.
