Don't do it mate, I did & wish I hadn't.
Changed over 2 in the house a few months ago & one of the boxes already failed (small sample size admittedly but off to a bad start with a new box). The multiroom experience doesn't work well for me, my wife's recordings clutter it up & I have to go searching for anything I've recorded, frustrating. Start-Up screen isn't last channel watched goes to home screen, frustrating. Subtitles: 6 key presses to turn off or on, frustrating.
On Demand is probably the (only) saving grace, easier/faster to navigate. They've renamed the 'last channel' button on the remote to 'tv', frustrating (for me anyway I keep forgetting which button does it, labelling it last channel kinda gave me a clue)
