15 // one title is built for each playlist
16 // playlist-0 is used as first-play item
18 // the basic idea is to use playlist-0 as a menu / directions to
19 // use the bluray player remote-control to select the desired title
20 // and start the play, avoiding the need for a menu system.
22 // if the first play item is the main title, that is ok also.
