This topic applies to Windows XP Service Pack 1 or later.
The SetDeinterlacePrefs method specifies how the VMR will select a deinterlacing mode if it cannot use the preferred deinterlacing mode.
Syntax
HRESULT SetDeinterlacePrefs( DWORD dwDeinterlacePrefs );
Parameters

If the VMR cannot use the preferred mode, it will fall back to another mode as specified by the dwDeinterlacePrefs parameter.
