How do I add subtitles to a DVD? I have to do a translation of the words of a DVD, and then add subtitles to that DVD (iso file or folder).

This is a professional work and it has to be clean (no change in quality, ie no "rip"...).

How can I add subtitles to a DVD (file) on a Mac (snow leopard)?


wysiwyg: being able to view the DVD / stop it to add the subtitle, set the duration easily
if possibly, set the font, size and position of subtitles
(if possibly, even add subtitles to the DVD Menu)


Is there already an App on the Mac that does that and just need a download?
Or a 3rd party software is required?
Final Cut Pro can do that.

So can DVD Studio Pro.

There are also some free alternatives, most notable: Aegisub and Jubler.
