Extracting Subtitles from a burnt DVD

[foofoohightec]

Hi,
I've burnt a Divx movie to DVD after embeding subtitles through VirtualDub. I need to extract subtitles from movie in order to change font size and embed them back to movie.
Bearing in mind that I am a newbie, is there a "simple" straightforward method to do this?! :scared:
Thanks in advance.

It would be easier to return to the original DVD and extract the subtitles with something like VobSub, especially if you hard-coded the subs onto the video.
