Panasonic PVR. Works perfectly for long periods but needs AC power down to regain full functionality. Like last night could not get Direct Navigator (List of recorded programmes) to work. Just got a black screen. Unplugged mains and all restored. Have set up Favourites1 and every now and then Catagory: All DVB channels comes back. Have to reset with Blue button. I can sort these things out but my wife cannot due to disabilty. If not for the glitches I'd give it 6 stars (out of 5).
