Selects the lower directional button from the displayed menu.
Syntax
HRESULT LowerButtonSelect(void);
Return Value
Returns an HRESULT value.
Remarks
On physical or electronic remote control devices, there is often a group of four directional buttons used for certain types of operations (such as menu navigation). This method tells DirectShow that something (the user, probably) triggered the lower directional button.
Selecting a DVD button simply highlights the button but does not activate the button. Selecting is the Windows equivalent of tabbing to a button but not pressing the SPACEBAR or ENTER key. Activating is the Windows equivalent of pressing the SPACEBAR or ENTER key after tabbing to a button.
This method returns an error unless the domain is DVD_DOMAIN_VideoManagerMenu, DVD_DOMAIN_VideoTitleSetMenu, or DVD_DOMAIN_Title. For more information, see DVD_DOMAIN.
