Swapping subtitles on multiple IFOs on a single dvd?

[nobodyhome]

A while ago I asked about swapping subtitles while keeping the pre-existing menus and was given a link to this tutorial, but I'm not sure how to apply that to the current dvd I'm working with.

Basically, I bought a dvd set and want to sawp the subtitles for custom subtitles. The dvd seems to have subtitles associated/in both the VTS_02_0.IFO and VTS_03_0.IFO. The dvd has seven episodes where VTS_02_0.IFO has sixe and VTS_03_0.IFO has one. I'm not the most computer talented so I could be wrong, but the tutorial seems to work for just one .ifo?

How can I swap the subtitles for both IFOs and remake the dvd if there are multiple subtitles on multiple IFOs? Is it even possible?

Thanks in advance for advice.

Extract the episodes separately, reauthor each episode with its new subtitle, stick all the episodes back in using VobBlanker. I don't know if it's any different than replacing a single video like a movie, but just takes longer. A helluva lot longer
