Just to be clear, a decrypted copy is generally going to be quite different from the original disc and in no-way '1:1 bit perfect'. Aside from the actual AACS decryption process, the extent to which they differ depends on the AnyDVD options you have enabled (region code removal, BD-Live, removing trailers etc). Once you have created a decrypted copy, you are more or less locked to your originally chosen re-authoring options. eg: You can't remove region coding from a region-locked, decrypted copy of a disc Edit: This may have changed in 8.0.3.0. Some users have had issues in the past with the 'ScreenPass' protected discs which occasionally require updates to AnyDVD or the OPD. If you ripped a decrypted copy before the title was properly supported, you would need to rip it again from the disc once it was properly supported.So what I was doing, which was keeping protection in order to seek 1:1 bit perfect copies was *actually* the worst thing to do, since it's actually the most risk-prone and unverified method.
This is why I personally rip discs to a protected ISO, then rip a decrypted copy from the protected ISO file to check for any issues (I'll normally delete the decrypted copy afterwards). That way I can be reasonably confident that the protected ISO is a 1:1 copy of the disc. I always have the option to make a decrypted copy from the protected ISO with any combination of re-authoring options. If any protection updates are required for AnyDVD/OPD, I won't need to re-rip the physical disc. And if it is a UHD disc which is not currently supported, I can rip it once and wait for support.
