PGC Program Map:    
    Program_1: Entry cell number 1 This program point is used by the chapter table.
    Program_2: Entry cell number 2  
   
Cell Playback:    
     
  Cell_1: Cell type (Angle) 3 Bitmask that contains some flags, that displayed in detail below:
    type normal can be normal or an angle cell
    Block type normal if it is an angle, this one specifies first/middle or last angle
    seamless playback linked in PCI: no is set to no, when SCR starts at 0.also indicates the layer break point.
    interleaved: no used with Angles or Seamless branching
    STC discontinuity: yes is always yes on a new VOB-ID. Means the playback time starts at 0.
    seamless angle linked in DSI: yes don't know what that means.
  Cell_1: Cell restricted? 0 ??
    restricted: no  
  Cell_1: still time (seconds, 0xFF = Infinite) 0 Used for still images
  Cell_1: command Nr (0 = no command) 1 if this is set, then it executes the Cell-Command nr, in above command table.
  Cell_1: playback time (BCD) 80 playback time of this cell.
     playback time (hh:mm:ss.frame) 00:00:00.10 / 25 fps  
  Cell_1: entry point sector 0 start sector in VOB file of this cell
  Cell_1: first ILVU VOBU end sector 0 just used with angles or seamless branching
