The DVDNotify event notifies an application of many different DVD events and disc instructions.

VidWebDVD_DVDNotify(
    ByVal lEventCode As Long, 
    ByVal lParam1 As Variant, 
    ByVal lParam2 As Variant
)

Parameters

lEventCode
Long containing the event code.
lParam1
Long that can contain additional information for this event.
lParam2
Long that can contain additional information for this event.

Return Value

This method does not return a value.

Remarks

The DVD Navigator filter and other filters in the filter graph send a variety of notification codes about the state of the disc and the file that can be captured with this event. These codes are often accompanied by parameters that hold additional information. See DVD Event Notification Codes for more information about the event codes and their parameters.

A good use of this feature is to capture domain changes to disable unavailable features for the new domain. If using this method, be aware that the DVD does not send a domain change method on startup.
