I was wondering if this were possible;

I have a movie that has Japanese subtitles I know I can rip the subtitles off of DVD to .sup format - I have Systran translator on my work computer, I never used it before but today I played around with it and it does have a Japanese to English translation but I would need to copy\paste the text (I know it will not be perfect but it would get me in the ballpark).

So I guess I would need to OCR the subtitles somehow to text (.srt)?? I imagine that would be a problem?
