There are hundreds of channels available. Go to the Roku channel and just start scrolling. Many are free and some are a subscription. I currently have Acorn for $5 a month and if I ever get caught up on all the programs, I may add BritBox. Another source is to google the shows and see if they list in their descriptions what channels they are available on. I see you are here in So Cal, try calling the embassy at ask the folks there or, if you are in the LA area, go to one of the expat restaurants and ask them. They probably have the available channels on their tvs in the bar area.
