Return Value
Returns an HRESULT value that depends on the implementation; can be one of the following values, or other values not listed.

Remarks
This member function can be used in place of separate calls to the CBaseControlVideo::get_DestinationLeft, CBaseControlVideo::get_DestinationTop, CBaseControlVideo::get_DestinationWidth, and CBaseControlVideo::get_DestinationHeight member functions. An application can change the source and destination rectangles for the video through the IBasicVideo interface. The source rectangle affects which section of the native video source will appear on the display; the destination rectangle affects where the video will appear when played. The destination rectangle is relative to the client area of the window in which it is playing. The upper-left corner of the window is coordinate (0,0).
