These subtitles are likely what's called ephemer subtitles, that is there is
no end date associated with them, they are just replaced when another one
Maybe if you could get us a sample of this vob, we could have a closer look.

Ok needs investigating, but afaik vlc discards the color information of the
subtitles so this might be why.

That is the expected behaviour. The command vlc:quit only takes effect when
the first input (dvd) is finished but DVDs with menus will never end ;).
What you want is to use the simple dvd plugin (without menus support).
vlc dvdsimple:@4 vlc:quit

The problem is that you can't move the subtitles outside of the picture zone
which is different from the video window area. The picture zone is the area
you get when the video is first opened (the video window is first set to
fit the picture exactly).
