been having the same issue now on and off for the past two weeks, lost count of the many 3 hours waits I have had to wait, sometimes it comes back on, but only for a couple of hours, when turning off at night I'm greeted in the morning with the welcome page then switches off then the green screen, will now get onto virgin and report it as I'm paying good money for bad service, this is my second box in a matter of months, always seems to happen after an update, they thought they were doing me a good turn by giving me the tivo6, hahahahaha funny not, now I suppose I will lose all my recordings.............
