How to add SRT subtitles to a DVD?

[sldvd]

I downloaded some subtitles in a .SRT file, and want to add them to a movie I have on DVD. I copied the DVD to my hard drive, so I've got the VIDEO_TS directory with multiple .VOB files in there. Is there a way using a free program to add the subtitles to the DVD? Doing it without having to re-encode the video would be best.

If you plan to burn this back to DVD then the question is "How to add subtitles to an existing DVD?" please see the thread

Yes I will be burning it back to a DVD.

Baldrick's guide here has never let me down.

It uses only free tools, keeps everything on the original DVD, and requires no re-encoding. Do note that the new subtitles must be selected by the Subtitle button on a remote control (or via the Subtitles option on your software player) as there is no menu entry for them.
