TwoSeven: Is working for me here in CHCH, just finished setting up my XB1. Only thing I cant get working at the moment is any form of TV guide. I have it connected to my Panasonic HD recorder and get a good picture - have not tried to control the HD recorder from the XB1 yet either.
Only issue I had was I needed to use the included High Speed HDMI cable to output to the TV. I had a good quality HDMI 1.4a cable but got a black screen, swapped them over and all ok.
On an aside, the courier left the box at my front door which is right beside the street and clearly visible to everyone so I was not really happy. The good thing was that the shipper (mighty ape) sent me an email as soon as it was delivered so I was able to go home and get it quite quickly.
