TV reception was smoothly before using the HD recorder in all rooms. After using the HD recorder of cable Germany, there were on some channels constant glitches on other only occasionally. After replacing the house connection amplifier there were temporarily dropouts. In recent weeks the picture was constantly smoothly (perhaps also the injected signal has improved). Because the amplifier offers 2 settings for an optimum signal, in the Installation Instructions, a tip for easy optmalen setting for laymen would be beneficial (therefore no 5 star).
