Xbox One uses Kinect as an IR blaster for channel changing etc.
Without Kinect, the console cannot control the TiVo or any other STB, which makes routing the STB through the console rather pointless, as you can't use OneGuide and still need the STB's remote.
There is a way without Kinect, though:
Xbox One also has a port on the back for connecting an IR extension cable.
