Trouble with 2 or more DMO objects

        // Add a DMO Wrapper Filter
        dmoFilter = (IBaseFilter) new DMOWrapperFilter();
        dmoWrapperFilter = (IDMOWrapperFilter) dmoFilter;

        // Since I know the guid of the DMO I am looking for, I *could* do this.
        //hr = dmoWrapperFilter.Init(new Guid("{7EF28FD7-E88F-45bb-9CDD-8A62956F2D75}"), DMOCatergory.VideoEffect);
        //DMOError.ThrowExceptionForHR(hr);

        // But it is more useful to show how to scan for the DMO
        Guid g = FindGuid("DmoFlip", DMOCategory.VideoEffect);

        hr = dmoWrapperFilter.Init(g, DMOCategory.VideoEffect);
        DMOError.ThrowExceptionForHR(hr);

        SetDMOParams(dmoFilter);

        IBaseFilter dmoFilter1 = null;
        IDMOWrapperFilter dmoWrapperFilter1 = null;

        // Add another DMO Wrapper Filter
        dmoFilter1 = (IBaseFilter)new DMOWrapperFilter();
        dmoWrapperFilter1 = (IDMOWrapperFilter)dmoFilter1;

        // But it is more useful to show how to scan for the DMO
        Guid g1 = FindGuid("DmoSplit", DMOCategory.AudioEffect);

        hr = dmoWrapperFilter.Init(g1, DMOCategory.AudioEffect);
        DMOError.ThrowExceptionForHR(hr);
