Like I said, only at a licensed replication facility. But you need professional authoring software to provide what the replication facility needs like Do Studio Or Scenarist. Encode will not output the files needed. It will also cost a pretty penny and required a minimum run of about 1000 discs. But, like I said, copy protection is really a waste of time and money unless you plan on releasing thousands and thousands of copies. Why do you feel you need copy protection? 🙂
No only at a replication facility. Why do you want it encrypted anyway? Pirating issues are only a concern for the studios which sell millions of copies.
