I’ve never bothered to scan a pressed DVD movie before, but I did today just to compare the results to that of a typical DVD+R backup. The results shocked me, but I’m guessing there’s an explanation.
The results for the pre-recorded source were simply awful. How awful? Well, I only got through half the disc before it failed. Average PIF was nearly 8, with maximum of 581. Total was over 112,000. PIE averaged 38, with a max of 962 and total of over a half million. Average jitter was over 11%, with max over 18%. The disc plays flawlessly in every player/drive.
I’m guessing that disc scanning utilities were simply not meant for pressed DVD’s, and are specific to recordable DVD due to differences in the way they interpret the pitting of pressed DVD vs. the dye/phase change of recordable. Anyone have any insight on this? Is my assumption correct?
