i have had this machine for some months now and only record from a satellite receiver - on some satellite channels although the picture on the monitor is perfect a message appears `no live signal` and if i dont press ok within a few seconds it stops recording- this happens mostly if there is a scene change or the adverts come on - is there any way to overcome this problem as it is wasting a lot of time and is very frustrating as some channels it is impossible to record from - jeff jones
