I have recently got a Sky+ box and, although very happy with the features, am dismayed at how slow the software runs in comparison with my old Sony box (which was a flying machine). On standard Sky digiboxes you can force a download of the latest version of the software by holding in the BACKUP button on the front of the box after you reconnect it to the mains. I have tried this with my Sky+ box but nothing happens. Is there a way of doing it on Sky+ at all??
