From what I've seen
- on these "Media is locked to region(s): 1!" Discs
- Is that AnyDVD can not - properly -
- Emulate the RPC-2 drive with region 1! ( or Drive's applicable Region )
- If it's not set to Region 1 - in the First Place

Emulating RPC-2 drive with region 1!
- Imports into Shrink 3.2 directly without any issue (and also reads without issue).
- Imports into Nero Recode 2.5.4.0 directly without any issue
- Imports into Clonedvd 2.9.0.9 directly without any issue
The only time I've witnessed setting a drive's region code being a factor is when Anydvd cannot decrypt css otherwise (or when using a Matshita drive). In those instances, Anydvd will provide you with an error message (and often the warning message can be ignored).
That's not to say I don't consider your suggestion valid; I'd just be very surprised/interested if setting drive region addresses "Copy Protection Error - The read failed because the sector is encrypted" error code messages in Shrink.
