You don't need "internet knowledge" to use iPlayer for goodness sake.

You do. You need to know how to set it up and then use it.

No you don't need "internet knowledge" for iPlayer, don't be so melodramatic.
It's just basically an app. If you can use an app on a phone you can use an app on the TV/Firestick/<insert device of choice here> where there is no need know anything about the internet. It just needs a connection.
