My drives are both region 1. AnyDvd is installed but does not initiate when a disc in inserted unless I go through the process of putting in a non-protected one first, then inserting a protected one. I have no problems once I can recognize the disc. This makes me think its a software issue, but to be fair - both these drives have ripped / burned enough discs to stretch to the moon and back. I don't mind replacing the drives, but why replace it if it ain't broke ya know?
