Abstract: Methods, systems and computer program products for copy protecting content data to be stored on storage media are disclosed. At least one location in the content data is selected for insertion of a predetermined data sequence, which, upon re-trieval from the storage media by a data retrieval apparatus, is capable of rendering the data retrieval apparatus incapable of correctly retrieving the content data from the storage media. The predetermined data sequence is inserted at the at least one selected location in the content data and the content data and predetermined data sequence are processed such that the data retrieval apparatus is capable of correctly retrieving the content data from original storage media the content data is stored on and is incapable of correctly retrieving the content data from a copy of the original storage media.

Abstract: Methods, systems and computer program products for causing recordable DVD storage media to be identified as non-recordable DVD storage media by a DVD drive are described. Data used to identify a recordable DVD storage media (100) as being recordable is occluded (step 190) to prevent correct retrieval from the recordable DVD storage media by the DVD drive. As a consequence, the DVD drive incorrectly identifies the recordable DVD storage media (100) as non-recordable DVD storage media.
