* DVDNAV_NAV_PACKET
*
* NAV packets are useful for various purposes. They define the button
* highlight areas and VM commands of DVD menus, so they should in any
* case be sent to the SPU decoder/overlaying engine for the menus to work.
* NAV packets also provide a way to detect PTS discontinuities, because
* they carry the start and end PTS values for the current VOBU.
* (pci.vobu_s_ptm and pci.vobu_e_ptm) Whenever the start PTS of the
* current NAV does not match the end PTS of the previous NAV, a PTS
* discontinuity has occured.
* NAV packets can also be used for time display, because they are
* timestamped relatively to the current Cell.

* highlights are reported this way. That means, when the button highlight
* has been moved around by some function call, you will receive an event
* telling you the new button. But when a button gets activated, you have
* to handle the mode 2 highlighting (that is some different colour the
* button turns to on activation) in your application.

* DVDNAV_WAIT
*
* We have reached a point in DVD playback, where timing is critical.
