Hello all.


I don't mean to be critical of the DVDFab software, but can somebody explain something to me?

Why is it that when DVD publishers publish a new DVD with a slightly different copy protection scheme, existing DVD players don't need to be updated to decode and play them, but backup software such as the DVDFab series does need to be updated to decode and copy them?

Is the way DVDFab reads and decodes DVDs fundamentally different from the way DVD players do it? And if so, then why is it different?

For example, an older version of DVDFab Decrypter could copy "Pictures of Hope", an infomercial DVD about an antidepressent drug called Effexor XR and create a playable DVD, but it was full of duplication glitches. But a newer version, DVDFab Platinum v 3.0.7.2 produces a glitch-free copy.

DVDFab Platinum v 3.0.7.2 can't make a glitchless copy of Spike Lee's :"When the Levees Broke: A Requiem in Four Acts": Disc 1. The result has multiple duplication glitches at the 38 minute and 59 minute points. But I imagine that a newer version will.

From what I've read in the release notes and other threads on this forum, this pattern of required updates has repeated many times.

So, to repeat my original question, is the way DVDFab reads and decodes DVDs fundamentally different from the way DVD players do it? And if so, why?
