i had success using rip it 4 me v1.8.0along with dvd dcrypter and dvd shrink.good luck my fellow mates!!!!!
I understand it works with v1680.Also, faster rip if check "Cycle tray after read error" in DvdDecrypter.
Unfortunately, the cycle tray option makes the rip slower for me, due to automatically ejecting the disc and respinning the drive after every encounter of protected sectors. So I leave it unchecked as the drive speeds up after the error.
