Streaming with the main television and cable box is a joke.

Trying to watch Paramount + or HBO/Max is a waste of time.  All it does is freezes and continues buffering.  This only happens on our main large screen livingroom television that is hooked up to the xfinity cable box. We don't have this problem on 3 other small Roku televisions we have.  Maybe switching to all Roku instead of Xfinity would be better.
