In a video recorder (2) having an electronically tunable tuner (19) and a connector (4) to which a cabling (6) can be connected, which cabling can also be connected to a connector (5) of a television receiver (3) which also has a tuner (46), at least one comparison device (69, 75, 130) of the video recorder (2) is connected to the tuner (19) of the video recorder (2) and to the connector (4) of the video recorder (2) via each time one connection (65, 66, 73, 77) in order to compare at least one component of one of the two received signals supplied by the tuner (46) of the television receiver (3) and applied to the connector (4) thereof with the corresponding component of the received signal supplied by the tuner (19) of the video recorder (2), which comparison device (69, 75, 130) supplies an inequality signal in the case of inequality of the signals applied to it, and an equality signal in the case of equality of the signals applied to it, the tuner (19) of the video recorder (2) being successively tuned to different stations when the inequality signal is produced and the tuner (19) of the video recorder (2) being kept tuned to a station when the equality signal is produced.
