Links to searches are broken after 4 or 5 days. The FAQ specifically mentions that error.
If you are ripping an ex-rental or second hand disc (ripping a rental may infringe the copyright laws in your country), the disc is damaged in some way - a scratch or smudge are the usual suspects.
If it's a new disc, it's hosed (waxed, damaged, whatever) - it's happened to me. Take it back for exchange.
>Nobody has successfully gotten around that error?
Yes, lots of us, by cleaning the disc, accepting irrepairable damage or exchanging the disc.
If DVD Decrypter, with fine and gross error control, can't do it, then it can't be done.
>DVD players don't have a problem with it ...
Playing and ripping are two different things.
