Signals the beginning of any still (PGC, Cell, or VOBU).
Boolean (BOOL) value indicating whether buttons are available. Zero (0) indicates buttons are available so the IDvdControl2::StillOff method won't work. One (1) indicates no buttons are available, so IDvdControl2::StillOff will work.
DWORD value indicating the number of seconds the still will last. 0xFFFFFFFF indicates an infinite still, meaning wait until the user presses a button or until the application calls IDvdControl2::StillOff.
All combinations of buttons and still are possible (buttons on with still on, buttons on with still off, button off with still on, button off with still off).
This event is raised in all domains.
