Found & removed 17 potential bad sector protections!
here is mine fresh out the package!!
Then why does the one that worked have 2 bad sector protections, and the one that failed have 17?
Log files from discs that worked need to be posted so they can be compared to ones that don't work. If people aren't willing to provide log files from the working discs, then confusion reigns.
amazing thing is that dvdfab 8.1.1.2 copies my deffective thor dvd. maybe keep looking for the solution instead of insisting the discs are all deffective
