How can I replace one subpicture with another?

[doctorjellybean]

I have a movie which I want to replace one of the subtitle streams with another. The current movie has English and Spanish subtitles, and I want to replace the Spanish with a Dutch one. I'm following this guide at the moment, but I'm not sure if that will do what I want

Any help would be greatly appreciated.

Thank you.

Yes, that guide is fine. I have done this several times and never had any problems.
