DirectDraw+ActiveMovie problem...

I want to know how my application can use DirecDraw interface from DirectX3 and the AvctiveMovie interface,
because now the  both in two different apps work fine
but in the same apps look's bad and the way it's look to
me I got to pass somehow to ActiveMovie de DirectDraw pointer I create but doesn't work like the way I think

here's my code where I initialize some interface for
ActiveMovie :

CoCreateInstance(CLSID_FilterGraph, NULL,                  CLSCTX_INPROC_SERVER,                                       IID_IGraphBuilder,(void **) &pGB);

pGB->QueryInterface(IID_IMediaEvent,(void **)&pME);
pGB->QueryInterface(IID_IMediaPosition,(void**)&pMP);
pGB->QueryInterface(IID_IVideoWindow,(void**)&vMP);
pGB->QueryInterface(IID_IMediaControl,(void **)&pMC);
////////////////////////////////////////////////////////////
// Why this query don't work like others ????
pGB->QueryInterface(IID_IDirectDrawVideo, (void **)&pDD);
pDD->SetDirectDraw(pDDraw);

Thank You in advance for your great help...

You have to init your interface like that

hr = CoCreateInstance(CLSID_VideoRenderer, NULL,                                     CLSCTX_INPROC_SERVER,
                                    IID_IDirectDrawVideo, (void **) &pDD);

Then you  can access like that

pDD->SetDirectDraw(pDirectDraw);

You have to know then DirectDraw can be initialize more then
once, so if you got a problem to Render a file, it's probably something else.
