A method for copy protection, comprising: providing audiovisual data or audio data having a genuine playback sequence defined by the content of the audiovisual data or audio data; dividing the audiovisual data or audio data into a plurality of portions (104-1,...104-4, 108-1,...108-4, 375-1,... 375-4, 372-1,... 372-6), the portions having a first order, wherein when the portions are reproduced in the first order the content is reproduced in the genuine playback sequence; determining a second order for at least a part of the portions, the second order being different than the first order; determining a physical position where, on the record carrier (114, 154, 160), a respective portion of the plurality of portions is to be stored dependent on the second order; providing at least one additional portion (145-2,...145-n, 375-3', 372-6') to be stored on the record carrier (114, 154, 160), the additional portion being a copy of at least a part of one portion from the plurality of portions (375-3, 372-6); including the additional portion (145-2,...145-n, 375-3', 372-6') in the second order; providing a plurality of further first orders to be stored on the record carrier (114, 154, 160), which further first orders are different from the first order such that when the portions are played back in one of the further first orders, the additional portion (145-2,...145-n, 375-3', 372-6') will be played back at a position according to the one of the further first orders; and determining program instructions to be stored on the record carrier, which program instructions, when executed on a reading device configured to playback the record carrier, read data at certain positions on the record carrier, wherein the first order is determined based on the data at the certain positions. providing audiovisual data or audio data having a genuine playback sequence defined by the content of the audiovisual data or audio data; dividing the audiovisual data or audio data into a plurality of portions (104-1,...104-4, 108-1,...108-4, 375-1,... 375-4, 372-1,... 372-6), the portions having a first order, wherein when the portions are reproduced in the first order the content is reproduced in the genuine playback sequence; determining a second order for at least a part of the portions, the second order being different than the first order; determining a physical position where, on the record carrier (114, 154, 160), a respective portion of the plurality of portions is to be stored dependent on the second order; providing at least one additional portion (145-2,...145-n, 375-3', 372-6') to be stored on the record carrier (114, 154, 160), the additional portion being a copy of at least a part of one portion from the plurality of portions (375-3, 372-6); including the additional portion (145-2,...145-n, 375-3', 372-6') in the second order; providing a plurality of further first orders to be stored on the record carrier (114, 154, 160), which further first orders are different from the first order such that when the portions are played back in one of the further first orders, the additional portion (145-2,...145-n, 375-3', 372-6') will be played back at a position according to the one of the further first orders; and determining program instructions to be stored on the record carrier, which program instructions, when executed on a reading device configured to playback the record carrier, read data at certain positions on the record carrier, wherein the first order is determined based on the data at the certain positions.
