Playlist = Player.RequestedPlaylist If Not Playlist Is Nothing Then ' Retrieve the IWMSActiveMedia object. ActiveMedia = Playlist.CurrentMediaInformation ' Retrieve the IWMSActiveStreams object. ActiveStreams = ActiveMedia.Streams ' Retrieve information about each active stream. For i = 0 To ActiveStreams.Count - 1 ' Retrieve the IWMSActiveStream object.
