Provided is an information recording medium (104) on which a first content and a program are recorded. A reproreproduction apparatus (1) includes: a first storage unit (221) in which a setting value set is stored; an execution unit (206) which executes the program; and a second storage unit (222) which the execution unit (206) can read and write information from/into. The program causes the execution unit (206) to execute steps of: writing (S803) the setting value stored in the first storage unit (221) into the second storage unit (222); comparing (S900) the setting value stored in the first storage unit (221) to the setting value which has been written into the second storage unit (222); and controlling (S920) the reproduction apparatus not to reproduce the first content, in the case where the comparing (S900) indicates that the setting value stored in the first storage unit (221) is different from the setting value which has been written into the second storage unit (222).
