MCI_OVLY_OPEN_PARMS
 
        The MCI_OVLY_OPEN_PARMS structure contains information for
        MCI_OPEN message for video overlay devices. When assigning data
        to the fields in this data structure, set the corresponding MCI
        flags in the dwFlags parameter of mciSendCommand to validate
        the fields. You can use the MCI_OPEN_PARMS data structure in
        place of MCI_OVLY_OPEN_PARMS if you are not using the extended
        data fields.
