Well... no ;)  I set the properties on the unconnected filter:

CHECK_HRESULT("Cannot create video encoding filter",
  (void **)&m_pEncFilter
// add filter to graph and connect pins

void configureVideoEncoder() {
 // Change settings

In the meantime, I replaced the value 400,000 in dsfTheoraEncoder.dll. This 
does the job for now.
