Seamless branching?

Does anyone know if it’s possible to do seamless branching on a home made DVD, and if so, what’s the best way to do it? I’m working on a disc of The Transformers: The Movie from 1986 and because there’s not too much difference, I’m mulling over the possibility of containing all four cuts of the movie known to exist- The US and European theatrical, the censored video releases, and a restored version of the season 5 airing with Tommy Kennedy segments and additional audio from the best source I can find, and video from the Sony DVD.

It really depends on what software are you using. Years ago I used Mediachance DVDLab Pro, that one was capable of doing it.

The basic principles :

• you need one “main movie”
• every alternate / extended scene should be encoded as a separate movie
• the main movie must have I frames put into exactly the frames which you will use as “branching points”, so you must use a mpeg2 encoder which allows you to do this. If you don’t put the “branching points” on I-frames, the branching will not be 100% seamless
• The main movie has to be split into chapters correctly.
• the last step will have to be the correct playlists in your DVD authoring software, so each movie version will have its own playlist.
