My Samsung Tivo box has been on 'start up' for the past 7 hours. I have done the online test of the box, rung 150 for support who told me to unplug and take out the co-axial cable and then assured me that the problem was a software update which would take 3 hours to re-set the box. He was confident that this was the problem. Evidently he was wrong and there must be a fault with the box and a new one is required. I hope that there is someone from Virgin media tech who might see this message and save me another lengthy phone call.
