I had been wondering if the comcast boxes would be providing this as a side door. (hdmi from tv going to cable box, cable box has net access ) When I asked about data sharing with these dvr boxes and the new streaming stick option, only thing they could tell me is that 'virtually all video decoding and streaming devices are sharing data with multiple third parties' I returned the dvr box, and have not chosen to use their new streaming stick.
