Electronic remote control devices typically have a number of buttons that activate various functions of a DVD playback unit. Typically, you call this method when a user clicks a button on the control device; DirectShow then indicates that the button was selected (by playing a sound or changing a graphic, for example) and calls methods appropriate to which button was selected, such as ButtonActivate.

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.
