  HRESULT hr = Create_MXFReader(&spReader); 
  if (hr != S_OK)
     return hr;
 
  //---------------------------------
  // Query IAVProperties interface
  CComQIPtr<IAVProperties> spProps(spReader);
  ATLASSERT(spProps != NULL);
 
  //---------------------------------
  // Set filename
  hr = spProps->PropsSet(L"source", L"file.mxf");
  if(hr != S_OK)
    return hr;
 
  //---------------------------------

  hr = spReader->Init();
  if(hr != S_OK)
