I see no need to download anything other than DVD Decrypter and the latest version of AnyDVD.
1.) Use ElbyCDIO as the I/O model.
2.) Disable the structural protection removal in DVDDecrypter.
DVDDecrypter will see the disc as unprotected and will continue to work... forever.
Another quote from Ollie
Setting Elby I/O in Decrypter will make sure, that AnyDVD is used. You can use SPTI as well, but you should avoid ASPI. ElbyCDIO is good, stable, runs on non Administrative accounts and is written by me.
Disabling the "structural protection removal" in Decrypter will make sure, that Decrypter won't touch the magic AnyDVD has already done.
