Main Window Video

Hi Everyone, I have gotten the code to render the video in a different window (Active MOvie window) up and running. (thanks to help i got from toymaker.com) I am trying to render video in the same window as my game but the following call fails.

if(FAILED(pVW->put_Owner((OAHWND)hWnd)))
		return E_FAIL;

this is the initialization of present parametres.

d3dpp.Windowed               = TRUE;
	d3dpp.SwapEffect             = D3DSWAPEFFECT_DISCARD;
    d3dpp.BackBufferFormat       = d3ddm.Format;
    d3dpp.EnableAutoDepthStencil = TRUE;
    d3dpp.AutoDepthStencilFormat = D3DFMT_D16;
    d3dpp.PresentationInterval   = D3DPRESENT_INTERVAL_IMMEDIATE;

    // Create rendering device object
    if( FAILED( g_pD3D->CreateDevice( D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd,
                                      D3DCREATE_SOFTWARE_VERTEXPROCESSING,
                                      &d3dpp, &g_pd3dDevice ) ) )
