DirectX 9 AudioVideoPlayback Error

[matt3011]

I've Tried to load video using AudioVideoPlayback.
It works well until I set Volume or Balance.
It doesn't show any error but the ending event is not raised for unknown reason.
When I don't set Volume or balance, this event is raised normaly.

If any one knows about this bug...

Private Sub ClipEnd(ByVal sender As Object, ByVal e As EventArgs) Handles ourAudio.Ending, ourVideo.Ending
        'Stop and restart our clip when it ends
        If Not (ourVideo Is Nothing) Then
            ourVideo.Stop()
            'myForm.EventPlayer(PLAYER_EVENTS.PLAYER_EOF, "", "")
        Else
            If Not (ourAudio Is Nothing) Then
             ourAudio.Stop()
             'myForm.EventPlayer(PLAYER_EVENTS.PLAYER_EOF, "", "")
            End If
        End If
