Try the Apple TV box. It's currently around £60 and works brilliantly. I use it to stream Netflix, BBC iplayer etc from my iPad. I long ago gave up on the Humax TV portal and just stream. You can use AirPlay on apps that support it or mirroring for others. A few actively block streaming - CH4 was one but I'm not sure if that's still the case as the ads were so intrusive I gave up on it.
