You can either use a recording TV, or use a recorder box.
It is easier to get a recording box, and if it fails it doesn't mean you lose your TV as well.

I've been looking for a Samsung expert, not a poor general information which I've known since I started using TVs and recording equipment.
I have worked on Samsung for over 15 years. How can I help you?
