Export your own "Play" function, declare the TMediaPlayer Component as
Global, or give it an access method within the form ...then call it from
your program

TMyForm * myForm; // Global to Module....

// Export this function
void PlayFunc()
{
    if (myForm)
        myForm->PlayInterface();
}

TMyForm::TMyForm()
{
    myForm = this;
}

TMyForm::PlayInterface( )  // MUST be defined as PUBLIC in the class
definition
{
    MediaPlayer->Play();
}
