Hello, I am currently building my own DVD of "Pirates of the Caribbean" from a HDTV broadcast.

I have a problem transferring the subtitles form a commercial DVD to my authoring.

I need to process the demuxed SUP-Files with a tool called subtitle creator. THis tool allows me to alter the colors of the subtitles as well as their vertical position (I prefer the subs being below the image itself).

After the authoring was complete I was happy cause everythig seemed to work very fine:

But when I burned this DVD and checked it on my TV (using the Hardware DVD-Player) I noticed the heavy flicker and bobbing of the subtitles.
I captured one frames with DSCALER:

You'll notice that the image itself is just fine. Only the subtitles itself are field swapped.

What can cause this kind of field swap and how can that be avoided?

I recall having an issue (not with subtitlecreator) where the subtitles had to be on an even vertical pixel (say 472 or 474), otherwise I'd get nasty flicker on a standalone. That's a possible explanation.

the subtitles had to be on an even vertical pixelAnd, if I remember correctly, "DVD SubEdit" forces vertical pixels to be even only...

And SubtitleCreator permits specification of an even offset, which means that so long as the user understands the issue, there is no need to change applications on the basis of only a single feature. Of course DVDSubEdit may be superior choice for the original poster for other reasons, but that is a matter for him :)
