There is a glaring weakness in this TV - It only has a single tuner so if you want to record a programme you also have to watch it at the same time - if you switch channels the recording stops. On a £2,000 TV I expected better. There is absolutely no point in recording on a tv with a single tuner. So don't throw away your humax!
In the USA much of the recording is done in conjunction with your cable tv provider. You just click the record button on the show or movie you wish to record. This can, of course, be done well in advance by using the programming guide provided by them.
In the absence of a sub 50" oled I bought a 49" Samsung qled which does have 2 tuners and the freesat picture quality is far superior compared to using my old humax. I hope the new LG CX 48" has 2 tuners but I suspect not.
