Xfinity gave us a new remote because the last one stopped working. We were annoyed because the new remote didn't have the replay button like the old one. There is a trick you can use to get the replay feature back. Shut your TV off and take the remote to a different room. Press Exit 3 times then press 0030. Go turn your TV back on and press Page Down. The show will go back 15 seconds. If you press Page Up, it will move ahead 30 seconds (if you are far enough behind live TV or a recording).
