Saw a box on sale in LeRoy Merlin (F) last week which plugs into your TV (SCART or HDMI) and connects via wifi to the internet. Box contains a hard drive, runs on Android and once set up you can download films and everything else off the internet and play them on the TV. No need for a local PC, you can even set your router up over the box.
If everyone else knows about this already don't flame me !
