I've just had Sky+ installed. For a while I've had no problems, but for the last few days I've been unable to record one channel while watching another. On checking the signals Input 2 has gone. When I turn off the box and turn it back on, it's all OK, but after a while the signal on Input 2 goes again, and I have to repeat the same process. I've tried to run the Sky+ and Planner rebuild, but the housekeeping process just freezes (waited for 25mins). As I have already recorded programs, I don't want to system reset, as I will lose them. Can anyone help?
