Subtitle doesn`t start even with Object > Specify Link
setting

hy folks,

The task I´ve to make sounds very simple:
I have a german video with english subtitles. So if u press the play movie
button, the movie should start without english subtitles ... and if u press the
play movie with english subtitle, the movie should start with the english
subtitle.
Here is what i made: The linked the first button normaly and it worket perfekt -
with no subtitle - in the simualtion, and linked the 2nd button (with subtitle)
with the specify Link subtitle 1 (en) setting.

I was pretty suprised, it worked all fine in the DVD simualtion in encore... but
when i burned it on DVD - it didn`t work...huhhu...

Then I tried to make an extra mark some frames later only for the subtitle to
start form in the timeline... so that i jump to an extra DVD marker when i press
the 2nd button... but this doesn´t work fine, because in the DVD Simulation i
see the subtitle is enabled, this is what the icon says, but the subtitle simply
doesnt show on the screen...

So maybe someone out there knows what to do... this has to be a very simple task
and I´m very suprised that this is a problem...
I´m sure that there is a solution.

Thanks a lot for u´r help
