Advertisements Today, I thought I'd try activating HBO Go on my TiVos... couldn't quite remember why I hadn't before. Anyway, I add the app, get an activation code, and go to the web site to sign up. And there, after I tell them my provider is Xfinity (and they log me in automatically), I get a list of supported devices allowed by the provider... and the TiVo isn't on it. This isn't a technical limitation. Comcast does nothing to provide HBO Go, except to authorize it (and as an ISP). The app is already there on the TiVo, only awaiting activation. And it's not like Comcast has a blanket policy against HBO Go -- they allow it on most of the supported devices, including Apple TV, which I set up right after all this. They're specifically discriminating against TiVo, for a reason that I can only assume is pure spite. Of course, this mostly makes me want to cancel HBO with Comcast and pick it up some other way, e.g. via Amazon.
