My whole family other than me want a "Smart TV" but i said we have a laptop that no one uses we could use that! So i need an OS that can display many channels and my dad wants HBO Go or something and also Chinese channels and movies... Any recommendations?
Just buy a Smart TV and save yourself the headache. My Smart TV is so much better for watching TV than anything I've ever built. Especially the remote control.
Unless you have a reason to need a computer that displays on a huge screen (i.e. gaming) or money is at a premium, it's more trouble than it's worth. If it's solely for watching TV, and playing blurays and dvds, or video files, a Smart TV is better in almost every way.
