Personally I don't mind reading DVDInfopro scans, as long as the program is set to show PIE/PIF as blocks, not as a line (in the scans above it's set to "line".. :(). Just got used to see scans this way, mainly to appreciate PIF density.
Apart from this, I can't see any significant difference leading to prefer other apps, at least not with recent versions of DVDInfopro. But as it's not really free, personally I stopped using it long ago.
@kg_evilboy: what makes you prefer the 2nd scan? Personally, I don't like the different (and higher) PIF density in the first GB in this scan... well, maybe it's only media variation, I admit, difficult to say.
