this functionality is provided through a simple API which provides the DVD
playback as a single logical stream of blocks, intermitted by special
dvdnav events to report certain conditions.  The main usage of libdvdnav is
a loop regularly calling a function to get the next block, surrounded by
additional calls to tell the library of user interaction.  The whole
DVD virtual machine and internal playback states are completely
encapsulated.")
