You all need a bit more patience!
My OH cannot follow programme plots etc and the words / music/ pictures and images all change too fast for her to process.
So she's OK with programmes where picture changes slowly, of the "plot" in v short bits - so she's OK with The Repair Shop, Countryfile, natural history programmes, Antiques Road Show, Escape to the Country, etc. Programmes or presenters become "familiar" to her even if she can't follow things properly.
So she looks at these during the afternoon.
Come the evening, when I want to watch TV, I put on what I want. She sometimes looks at it, or more usually nods off intermittently, and occasionally and v annoyingly "heckles" the programme with her incoherent "talking" or making noises, which I have trained myself to ignore! Some harmony amongst the disharmony.
I said you need patience, because unfortunately your OH will deteriorate and in due course will pass the stage of "wanting" a particular programme or wanting to hog the remote control. My OH no longer knows what the remote control is or how it works or what it for!
Just my thoughts.
