Do tell mummy to cheer up, help is on the way.
I have an ordinary TV, a set-top-box and (sigh) an indoor aerial. [and I would get better reception at a Tory fund-raising rally than I get from this set up]
Nevertheless. Once the box is tuned-in it is a simple task to delete all that I don't want, I sometimes miss a few basic channels whilst retuning, but 'gay-rabbit' and others like it always seem to be there. I just try again.
If only mummy had loving offspring who could do the needful....
The ONLY good thing to come out of all this plethora are the channel+1 channels. Coupled with the slightly less helpful 'opportunities to view again' this often means I have to fall back on the internet in order not to get word perfect, but I soldier-on.
