1) logically grouping elements
2) knowning the corresponding DVD level (SS, PGC, Program, Cell, etc) of
this group (through the corresponding CodecPrivate)
This way when you encounter a JumpSS you are going to jump to that
group. It would be much complicated with a flat list because each cell
(the lower level of DVDs) would need to contain the SS, PGC, Program it
