Had a new V6 box couple of weeks ago. There seems to be a generic problem with some recordings. When you playback recordings after around 5-6 minutes the whole system shuts down and reboots itself. When you play again it reboots at same place. Only way round it is to fast forward through that time slot. Has happened to a few program recordings. Tech support say they will try to resolve problem but at moment feel like returning box and replacing with the old TIVO which worked great.
