// New interfaced introduced into the WindowsXP SP1 release of the VMR.
// This interface allows applications to control the DX-VA deinterlacing
// support provided by the VMR.
//
// The VMR needs to be set into "mixing" mode for this interface to work.
//
// SetDeinterlaceMode is only effective for new connections made to the
// VMR.  It should be noted that the graphics device driver may refuse
// to use the specified deinterlace mode, in which case 3 fallback
// policies are offered by the VMR, these being:
//
//      1. Fallback to the next best mode offered by the driver.
//      2. Fallback to the BOB deinterlace mode.
//      3. Fallback to the WEAVE deinterlace mode (ie. turn deinterlacing off).
