Freeview has been somewhat rubbish for us ever since it started, so we installed FreeSat years ago. Not sure how long that will last....
We have 3 Humax FreeSat HD tuners, one is also a recorder.
On Freeview it's very weather dependant as to which of two transmitters, both about 30 miles away, "wins" the tuning battle. And which channels are actually detectable/watchable.
That said I'm currently watching Portillo on Ch5HD on my PC with a Hauppauge tuner picking up Freeview from, I think, Crystal Palace.
