There is an event in the TMediaPlayer that is a better place to turn it off. I think your mediaplayer is running into the situation where it wants to play something but nothing is assigned to it.

The TMediaPlayer is turned off ontimer event. Here is the snipet of source code procedure TForm1.Button1Click (Sender : TObject); begin ...; ...; Form1.GetItemData( itemnumber) ; end; procedure TForm1.GetItemData( itemnumber : string); begin ...; ...; if mediaplayer_ ON then begin Form1.MediaPlayer1. Stop; Form1.MediaPlayer1. Close; mediaplayer_ ON := false; end; mediaplayer_ ON := true; Form1.PlayMP3Music; end; procedure TForm1.Timer2Timer( Sender : TObject); begin ...; ...; ...; if mediaplayer_ ON then begin Form1.MediaPlayer1. Stop; Form1.MediaPlayer1. Close; mediaplayer_ ON := false; end; end; The PlayMP3Music is not within a thread object. Initially i didnt think it necessary to have it threaded. But now I wonder if that might fix it. I may try that in a few days time. Hope that helps explain the case.
