Please help me understand what I am looking at.

I've burned a ton of discs and thought I would understand and review the various 'testing' proggies.

I can't use KProbe so Nero and DVDInfoPro are my options (are there others?)

Speed Test - DVD info Pro... what does this scan tell me?



Read Test - DVD Info Pro .... all sectors read... that is self explainatory.


Nero Test -- What does this tell me?



Also, I thought that these two tools supported PI / PO analysis. What is that ? How is that measured? Do I care?
