Reauthor problem

[tepman]

I want to add a subtitle to a dvd so I demuxed the, video, subpicture, audio, etc to a folder and then I used muxman to make the vobs, I replace the vob videos in my original folder, then I used ifoupdate with this options.

The problem is that in powerdvd before I play the movie in the menu appears the old dvd stuff

When I am in the movie and do right click appears the right stuff
