I am just guessing and speculating here, but I do note that Wild Things 3 is another "Sony / Columbia" DVD, which means it is most likely that it has the Sony ARccOS copy protection on it.This is the "structure protection" scheme, and it is NOT the same as "RipGuard."
If I am correct, then DVDShrink will not rip this, straight from the DVD. DVDDecrypter's latest version will, with no problems, although you may see some messages go by that appear to be error messages, until you understand them.
And, as mentioned above, this could all be cleared up easily if the originator of this thread would just post the complete log. As always.
Personally, I have serious doubts if this is "Ripguard."
