I cannot confirm, that a local declarations of the MediaPipeline or any 
other MediaControl makes a difference (V3.18.4). I tested it with the 
given example and the result was exactly the same. I am assuming that a 
Quit command is equal to a click on the stop button of the IDE which 
also preserves the contents of the mp3 file. I informed Benoît about 
that in an email which I sent mistakenly to his personal account - my 
apologies.

I just tried to run the given example as a non-GUI-application and can 
confirm that the mp3 file is not emptied when doing this:

...

     pl.play
     Wait 20
     pl.Stop
     pl.close

This also worked with the GUI-application, but when I closed the FMain 
(without any further command) the mp3 file was empty again. Does FMain 
act as a media container which fills the mp3 file and kills its content 
when being closed?

When the non-GUI application is brutally terminated by clicking on the 
stop button of the IDE or by imposing a Quit command the contents of the 
mp3 file is also preserved. But the same happens with the GUI version.
