Getting Sky multiroom HD is now cheaper with the new non-PVR digibox.
What does this mean? Well you can buy one of these boxes for £50 and use it to view Sky HD in another room. However, as this is not a PVR there is no option to record any Sky content.
On top of your fifty quid there is still the £10.25 per month multi-room subscription and you will also need the £10.25 a month HD pack too.
