I HAVE SERVICE WITH YOU CAN I WATCH TV WITH MY SERVICES FROM YOU ON MY LAPTOP OR DO I HAVE PAY EXTRA? IF SO HOW CAN I PERFORM THIS METHOD FOR MY LAPTOP?
There is no extra cost as long as you subscribe to Xfinity TV service. You can access it on a computer at https://tv.xfinity.com or on iOS/Android by downloading the XFINITY Stream app from your respective app store. You will need to sign in with your username and password, which I assume you have since you were able to post here in the forums.
