Why would my Sky+ box need unplugging every day to get the + functions working. Initially I thought maybe the HD was on the way out, but now I'm thinking its software related.. any clues? The problem is, the box works fine in the evening and I'm able to record several programs, play them back, live pause etc without any problem. But, the next day when I arrive home from work the box says "Please wait" when I access the Sky+ Planner, and none of the recording functions work. If I unplug it and reboot, it works fine again...until the next day when the same thing happens again. Its done this 5 days on the trot, and it can't be trusted to record anything when I'm out. I've tried 'housekeeping' and a forced software update, but neither helped. So, does the HD need replacing, or is it something else?
