  1. Thank you!! I have been trying to figure out how to do this for months and not even Xfinity support could tell me how!!

  2. This is not auto tune.

    What people expect when they say “auto tune” is to have the device (in this case) automatically switch to a particular program or channel at a given time.

    There is currently no way to really do this with xfinity. You can set the box to “remind” you that a program is going to start, and it will ask you if you want to go to that channel: but that reminder will remain on the screen for an unlimited amount of time until you give it an answer or cancel it. This also isn’t really autotune.
