Some people may wonder how close dvdinfo scans on new 3.xx software compared to other scanback packages. Well I did some testing and I will post 3 scans all 3 scan are of the same disk, this disk has 3gb of video on it and was burned using nero 6.3.1.17. on my new benQ 1600 fw B5G9, then scanned for pie/pif and jitter on nu tech, benQ , and for pie/pif on liteon 832.
As you will see the level are all within 5% or less...not bad if you take into account that no drive will ever scan the same as another and, at least in theory, no two scans on scan drive will be identical.
Nu tech 082 fw B375
Incidentally, pay close attention to the fact that the scans are resulting in level 2 spikes in almost EXACTLY the same locations...very interesting!
