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 
refers to.
