Just received a new 372 box and seems OK. Problem is that I have recordings on there old 370 box that I want to watch. By swapping the boxes out I can do both but want to try to have a smoother change. Thinking to set up both boxes but without internet connection to the older box from which I will only watch recordings. I realise that if both boxes are powered up then both will react to the remote command and switch on. Thinking to physically block the infra red receiver on the second box when not using and to alternate between boxes by changing the box being blocked. Am I crazy and will this work or does anyone have a better idea.
