I have a friend who will be staying with me as a guest on and off indefinitely. He is going to buy a Roku TV for the guest room. I have a Roku TV in another room and watch thru the Spectrum channel plus I have a cable TV with a cable box and a Roku box on another TV. I'd like him to be able to watch as a regular guest and not a temporary one and be able to access the Spectrum channels I pay for and watch through the Spectrum channel on my Roku TV. Is this possible and can we watch two different things on different TV's at the same time? I'm confused on how to accomplish this, if possible, so we aren't paying for services I already pay for yet can remain independent from one another while watching.
