Well I already have jellyfin running in a container, just have to figure out how to get mum's TV to work with it I guess
log in on a local IP and not the network name and it's working again. but I'll be moving to jellyfin from now
I use an nVidia Shield for it. There's probably cheaper ones, but you tend to get what you pay for, and I've got a few 4KBR remuxes that even that struggles on.
