… It sure is effective. In trying to backup DVDs put out by this one specific company, often the ripper (DVDD, Clone, Recode, VOBlanker, etc.) will encounter an unresolvable read error somewhere between 40-50% on DL discs.
Sometimes these discs will play in a set-top player, w/some skipping/freezing at the problem area, and then may continue w/out incident. Or, I’ve had one or two that completely freeze the player, and require an eject to resolve.
My conclusion is that this company often issues extraordinarily poorly mastered discs, rather than it being any new attempt at copy protection. But while there may be just a momentary interruption in viewing on a set-top player, the effect is that is brings rippers to their knees.
Before you ask, yes, I’ve tried cleaning several times, and I have four different brands of burners in my system that I try the discs in. I use my Lite-on generally because it’s the fastest ripper, but it sometimes has problems w/damaged discs. When that happens, I go to my BenQ or LG–and if they can’t extract an image, nothing can (that I know of).
I’ve gotten pretty good at burning in general, and rarely burn coasters anymore, but I’m aware that many of you possess very arcane and intimate knowledge of the structure of DVD video files that far exceeds my own, and there is probably a way around this. I just don’t know what it is. If any of you have advice, or can point me in the right direction–a program to use, a guide to read, anything–I would be grateful.
