It addresses a different problem, but I don't think the tool you are looking for is out there.
Part of the solution in that thread was for the creators of the caption file to send it to him.

3. Re: How to extract closed captions from DVD
peacebreakerr Jan 13, 2014 1:19 PM (in response to peacebreakerr)So there may be more to the mystery: I was just fooling around with the disc and I now believe that it is a subtitle track rather than CC. Turning on/off captioning on DVD player (mac) does nothing. However, when I go up to Features>Subtitles it does not expand to show the tracks (whereas if I go to Features>audio it will show the two audio tracks to choose from). Now I'm more confused because the various subtitle programs I had used weren't seeing a subtitle track, which led me to beleive that it was captioning in the first place.

peacebreakerr Jan 14, 2014 9:49 AM (in response to SAFEHARBOR11)I've tried CC extractor and it doesn't recognize any CC on the DVD, which lends evidence to the fact that they may be subtitles. However, it seems like none of the subtitle programs are seeing a subtitle track either!

Stan Jones Jan 14, 2014 9:55 AM (in response to peacebreakerr)When are you seeing it on screen? Under what conditions. A remote should be able to turn on/off cc or subtitles.

6. Re: How to extract closed captions from DVD
peacebreakerr Jan 14, 2014 11:18 AM (in response to Stan Jones)Mystery solved! As I was writing a long description of everything I've tried I came to a realization:
1) Neither the CC nor subtitle buttons did anything on a blu-ray player, TV, or computer.
2) None of the programs I tried were seeing a subtitle or CC track
3) Therefore the subtitles must be hardcoded into the video
4) But mpeg streamclip and handbrake both showed only one video track.
5) Therefore the single video track must contain both versions of the video.
I went back to the mpeg2 I had demuxed with mpeg streamclip and sure enough, it was twice as long as it should be. I skimmed through it (which I hadn't done yet since I was so caught up with the subtitles) and saw the clean version and then right after, the subtitled version. The original DVD authors must have made a script so that the buttons would only play whichever half of the video track you chose.
If I had only double-checked the mpeg2 after demuxing it I wouldn't have wasted so many hours of my life!

That wouldn't require scripting, but it could make it confusing to reverse engineer!
