A DVD+R is not the proper mastering medium for what you are trying to do.
When you master a DVD with copy protection, you add the copy protection keys to the project settings, and then write the project to DLT tape, and send the tape to the replicator. Your replicator should know that it’s not possible to add copy protection to a burned DVD. If they don’t know that, you don’t want to be dealing with them.
To sum up- it’s not possible to write copy protection (CGMS CSS and/or Macrovision) to a burned DVD-Video disc. It can only be mastered to a DLT device. Sorry for the bad news, but maybe it actually helps.
