I trying to get WMP 9 to fire it's EndOfStream event and then play another video but it will not fire. Anyone please help!

Here is my code:

Private Sub Form_Load()
WindowsMediaPlayer1.URL = "e:\mpegav\avseq09.dat"
End Sub

Private Sub WindowsMediaPlayer1_EndOfStream(ByVal Result As Long)
WindowsMediaPlayer1.URL = "e:\mpegav\avseq10.dat"
End Sub
