A content distribution system (300) has access control according to a predefined data access format. A studio (32) provides content data and related proprietary data on a record carrier (34) to be rendered by a rendering device (39). In the system applications (35) are executed on the device for manipulating the content data and related proprietary data. An access policy is set for each studio that controls access to said content data and related proprietary data. According to the invention a cross access policy is set for a virtual entity (42), and at least part of the proprietary data (43) is made available according to the cross access policy of the virtual entity. Also a cross studio application (41) is provided that complies with the access policy of the virtual entity for accessing said data for enabling the rendering device, when rendering the record carrier, to execute the cross studio application for accessing, for a multitude of studios, said at least part of the proprietary data.
