Hello again,
Thanks for taking the time to reply. I think I wasn't clear about what I meant with regards to JAV titles with hardcoded subtitles. I didn't mean to do the conversion to softcoded subtitles (and later on to do the machine translation to any other language which is the easy part) using any of your development tools. What can be really helpful is to make a list of JAV titles that have hardcoded subtitles in any language, preferably in Japanese. It seems to me that finding a JAV title with any sort of subtitles is like finding a needle in a haystack, so at least if you come across a title that has it, mark it as one that has hardcoded subtitles in your updated list. It is then up to the individuals to decide what to do with this information.
