Swapping tracks

[Ginger]

Hi all,
this is my first post in this forum
I have made my first experiments in videomaking and DVD authoring, using this site as main source of information! Neverthless I have a small problem I wasn't able to solve myself using the "How to" section.
I wish two swap two tracks in a DVD (audio or subtitles), so that e.g track 2 becomes 1 and viceversa. Of course, without de-mutiplexing and remultiplexing the streams.
I guess that IfOedit should suit for this purpose, although all my attempts so far have failed
Can anyone help me with this?

Not possible without de-multiplexing and remultiplexing the streams (or changing the complette stream with a hex editor, as this info is distributed in several headers inside the stream).
The only thing you could change is the command in the menu (if any) that activates either stream. Therefore I would use pgcedit...
