It's failing when NMSDVDXLib.DVDEngineXClass:add_OnTrackFileWarning is called.
This method is part of an event (it adds an event handler). It's implemented as
an internal call on a ComWrapper class, so mono expects to wrap a COM method.
To find the IID of the interface that has this method, it looks up the
GuidAttribute on the interface that implements the method. That interface does
not have a GuidAttribute.

It does, however, have a ComEventInterfaceAttribute
(http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.comeventinterfaceattribute_members.aspx).
This attribute points to a more normal COM interface type (SourceProvider) and
another class that apparently implements add_OnTrackFileWarning
(EventProvider).

Somehow, I think that Mono has to account for this ComEventInterfaceAttribute,
but it's unclear to me how the EventProvider class is supposed to work.
