Hello, looking at the quartz.dll sources (filtergraph.c file) noticed the following:

static HRESULT WINAPI GraphBuilder_Connect(IGraphBuilder *iface,
    				   IPin *ppinOut,
    				   IPin *ppinIn)
{
    ...

hr = IEnumMediaTypes_Next(penummt, 1, &mt, &nbmt);
    if (FAILED(hr)) {
        ERR("IEnumMediaTypes_Next (%x)\n", hr);
        return hr;
    }

if (!nbmt) {
        ERR("No media type found!\n");
        return S_OK; // is this really OK? - DL
    }
    ...
}

If the pins were not connected - is S_OK the suitable return value?
