As far as I remember, I do use the account set up on the laptop for the TV, I just never watch on the laptop, but I ought to go in and subscribe to the channels on the laptop - is that right? It makes sense...
As to showing my favourite channels - YouTube seems very weird (on the TV). It shows me more of the same as I have been watching but it doesn't seem to be able to show much of a choice - for example, I've recently been watching lots of history documentaries. My suggested viewing is now FULL of that, and I have to struggle about to find stuff linked to (for example) ghost stories - which is what I was mostly watching a couple of months ago. Like YouTube has a teeny tiny short term memory and can't keep in its head that I leap about between history documentaries, the paranormal, the Met Office and psychogeography.
As far as it is concerned, I watch history and nothing else.
