Yes , whether it is rebooting I dont know , but as I said ..........I sit and watch tv.....the picture disappears, and comes back 10-15 seconds later, try watching a footie game and a penalty has been awarded the player goes up to take it and....NO picture !! it comes back 10-15 seconds later !! ( this actually happened to me !! ) As I said I switched boxes with one in livimg room...NO problems at all ..watched the rest of the match and no problems,,,, ( this by the way happens on all stations ) I put the "faulty" box on inliving room and the same happens ..picture goes away ...I have rebooted the box numerous times, ..left it off for a day, and still the problem persists,,,yet the diagnostic according to Virgin states no problems !! Getting really peed of now with them,,,,,,,,have even rebooted the router as well ! I was on chat for help, and was more or less called a liar when I told the moronic girl that the other 2 boxes were working fine and she told me they weren't...and would send an engineer round on or before the 15th....never arrived and someone was ALWAYSin !!
