I'd like to watch videos while eating instead of talking with my dad
Why would you prefer videos instead of talking?
We always have the same conversations while sitting on the couch. It's boring.
I understand what you are saying  but even if you find talking over a meal with your father boring, he might really enjoy the interaction. You'll have plenty of time to watch videos in your life, enjoy the time you have with your dad while you can.
The only reason we have the same conversations is because he refuses to learn of the real world.
You should enjoy your time with him, and try to slowly introduce him to more things.
