Functions
E_MhegErr	DVB_MhegPvrMakeBooking (S_STRING crid, S_CRID_DETAILS *details)
	The function adds an event to the PVR’s list of scheduled events to record. The type of CRID can be any of a single programme or series. The type is defined in crid_type to aid the PVR in finding the required CID. Where the CRID is a series CRID the booking relates to all programme events that are part of the series. The PVR is required to validate the CRID and check that resources are available for the booking. This may involve searching for multiple instances of an event until one is found that does not clash with a previous booking. Where no such instance is found the PVR may choose to indicate the conflict to the viewer, giving them the option to cancel one or more of the bookings. Each 'booking' in 'details' has a logical 'OR' between them. So receiver should choose one booking. The PVR must be able to record all 'locations' for the booking to be successful. The platform implementation of this funtion should only return MHERR_CONFLICT when it does not ask the user, via the native GUI, for input regarding conflicts. If it does ask for user input, then it should return MHEG5_RESULT_PENDING, and subsequently call MHG_NotifyBookingResult() More...
