Unfortunately, burned discs (disc that are created optically in you DVD drive) do not support CSS or Macrovision Encryption- in order to encrypt a DVD you need to replicate (physically have them stamped at a facility) your discs which usually requires an order of 1,000 or more. If you intend on creating at least a few hundred you might be able to find a replication facility to help you out- but if you only want to make a handful- you're probably out of luck.
The reason (from what I understand) is that you actually have to pay for the license to use these proprietary technologies - the fees are included in replication costs and the actual licensing is handled by the replication houses - it's not supported on burnable media because there's no oversight to the legitimacy of the content you're burning in the privacy of your home.
