Personally I'd go for Linux receivers. They can do everything the Freesat PVR's can and more, at a similar price. EPG is fantastic, they will mimic the channel numbering of Freesat or Sky. With ABM they automatically update the channel list. They can read a Sly card, and many others. You can stream to any PC or laptop to any room without a tv. And now with the OnDemand players from OpenViX you can watch iPlayer and other on demand services without a VPN or Proxy.
Put a twin tuner box in the main room with a hard drive (say 2T
. And in the kitchen and bedroom put single tuner boxes (without hard drives). All 3 boxes will be able to record and playback from the harddrive in the main box so it will be kind of like running a 4 tuner box. And for recording terrestrial just add a USB stick. Pricewise there are some top quality twin tuner receivers in the 250GBP range, and single tuner receivers for 140GBP, all 1920 x 1080 HD capable. An don't believe all the nonsense about these boxes being difficult to set up; this is 2013.
