Subtitle sync/joiner

[longwood]

I have a DVD that I bought while I am in Japan but it doesn't have any English subtitles. I found a program ffmpegx that will allow me to add a subtitle file to the dvd and burn. However the subtitle files that I have found on the internet are off in their timing by a little bit. So I was wondering if there is a program that will allow me to sync the subtitle file with the video file from the dvd. I found a program, subsyncx, but I can't download it from anywhere. I also found a subtitle file that is split into 2 parts, which is timed perfectly with the movie, but it has 2 parts. So I either looking for a subtitle syncing program or a subtitle joiner. Or if someone has subsyncx and wouldn't sending to me that would be great too. Thanks.
