Syntax
MediaPlayer_DVDNotify(Event, Param1, Param2)Parameters
Event Value that resolves to 264 if this event occurs. Param1 DWORD value containing bits for all user operations, indicating which commands the digital video disc (DVD) explicitly disabled. Each bit in the DWORD represents the state (valid or not valid) of a user operation. If the bit corresponding to a user operation is set, then that user operation is not valid. For more information, see Remarks. Param2 Zero. Remarks
The value of Param1 is a bit field defined as follows:

For example, if no buttons are present, the ButtonActivate method won't work, even if the method is not explicitly disabled.
