A:AnswerYes! It Roku has an Xfinity Beta app, and you can watch the same shows and channels on it, including On Demand, Saved, and purchased movies/shows
A:AnswerYes you can watch live TV on it. We have 2 of these and 2 ultra models, both are great. The express is smaller and easier to manage on an extra tv like in a camper or a bar, where we have our two express mounted
A:AnswerYes. You can search for the apps (streaming video) that you want to include in your library. For example, I downloaded YouTube TV and it gives me access to everything I used to watch via my CATV company and set top box. I no longer have any set top boxes in my home.
A:AnswerYes it will; a model like the Streaming Stick+ or Ultra may be better for Youtube TV, on the tv you will use most often, the Express works well as a secondary device
A:AnswerYes, I just looked it up using the search feature on my older Roku stick so I'm sure it's there on the newer versions though it does require a subscription.
A:AnswerYes it will, though a more powerful Roku like the Streaming Stick+ and Ultra may be a better option on your primary TV. The Express works great as a secondary TV
A:AnswerYes it will handle it, just depends on how often you will use it, as the Streaming Stick+ will handle i slightly better if that TV is further away from your router
