A machine controls a device configured to record media content in accordance with a recording schedule. The machine detects that the device is scheduled to record first media content. The machine accesses a first vector that describes the first media content and in which a first value of a dimension indicates whether a data track exists in the first media content. The machine detects that the device has access to second media content described by a second vector in which a second value of the dimension indicates whether the data track exists in the second media content. The machine may then determine that the first media content is a version of the second media content, based on a comparison of the first and second vectors. The machine may next determine whether the scheduled recording of the first media content is to be performed or canceled by the device.
