I'm trying to find a way to take a set of homemade subtitles and add them to an existing DVD (or replace the existing substitles which are poorly translated) with IFOEdit, then burn to DVDR. The closest guide I can find is:

http://ifoedit.wh.fr0zen.com/remux.html

which tells you how to replace the m2v video file. If you can replace the m2v video file, then there has to be a way to replace/add subtitles as well but I just can't seem to figure it out.

In the past I've de-muxed the VOB files to elementary streams (ac3/m2v), run chapterXtracter, and MaestroSBT to make all the assets I need to re-author with DVD Maestro. But I really think that there must be an easier way to do this w/ IFOEdit. Thanks in advance.
