My brother was trying to rip a DVD he had with the title The xxxxxxxx. It kept hanging using DVD Decrypter so he downloaded DVDFab Decrypter when ran to completion. Success? Not entirely. Post burn playing using PowerDVD revealed flaws which I can only describe as artifacts, but clearly the image suddenly degraded into boxes and swirls, but just as quickly corrected itself. Three of these flawed spots were rather early in the movie. I then directed PowerDVD to play the ripped files on the hard drive instead and discovered those same errors at the same moments in the movie. This, to me, meant the error was in the rip, and not the burn. Using my computer and DVD-RW drive I got far superior results in both the hard drive files and subsequent burned DVD.
Now, my pc is dual core with 8X the memory, but my LiteOn drive seems better than his Sony, and that seems to me the difference.
