TV Answer Man, can you watch Comcast’s Xfinity service on Roku? — Tom, Bowie, Maryland.

Tom, you can watch your complete Comcast video lineup on Roku, but you also need a Comcast/Xfinity video set-top and it has to be activated. Confused? Okay, let me explain.

Comcast has an app on Roku called Xfinity Stream that allows you to watch the same channels that you subscribe to via your Xfinity X1 set-top. For example, if have the set-top connected to a living room TV, you could watch your Comcast programming lineup on another TV in a different room by simply connecting the Roku to the second set.

This is a nice feature for Comcast subscribers who want TV in multiple rooms without paying for additional set-tops because, at least for now, the Xfinity app does not require an additional fee. (Note: The Xfinity Stream app is also available on smart phones and tablets.) Comcast’s video services are available on the following Roku devices:
