Posting so others in the same situation will find an answer when searching Google... In September 2019, I received a letter from Comcast/Xfinity (Seattle) saying that my subscription to NHL Center Ice would not be renewed because my "TV box" is incompatible and needs to be replaced. I've enjoyed NHL Center Ice via my TiVo Premier for a few years, so I suspected that it was a mistake, given that I also have an Xfinity SD box in my home. But my calls with Xfinity and online research have shown that it's true: they are now limiting NHL Center Ice access to those customers with an Xfinity X1 box, and I'm not getting rid of my TiVo. So it now appears that my only option for watching out-of-market hockey (which, in Seattle, is all hockey until 2021) is NHL.tv. I haven't checked my TiVo yet, but hope that there's an app for that - perhaps if there's an app only for newer TiVos, this will finally push me to upgrade to a Bolt.
