Xbox live tv not working. Lost signal. Motorola rng150n

I too am having this problem. Cable box is a

Motorola RNG150N from comcast. It is simply wired from hdmi on cable box to the xb1

Haven't had this issue with tv but netflix and movies.

Thinking maybe a different hdmi will do the trick?

just using tv speakers as well.

I keep having issues with the freezing, but I also keep getting the "we've lost your TV signal, please make sure your cable or satellite box is on and plugged in to xbox one" (or something to that effect), then my picture will come back frozen, then work
for about a minute, then freeze, and on & on. I am sooooo frustrated! Just wondering if you also got the lost tv signal message as well? I have HDMI splitter, but it's not powered. It's just a little box that does 3 into 1. Not sure if I can do anything with
it. My cable box is a Motorola from Cox Cable, DVR, HD btw

It's definitely Macrovision Copy Protection in my case.

I tied my other cable box and all is good.

Bad: Xfinity Motorola RNG150N

Good: Comcast Pace RNG110

The models are as displayed on the front and how Xbox One picks them up automatically.

I just upgraded from day one to elite. Day one worked fine. But mine is a Comcast RNG150N. Send double the signals. I've tried old remote code and multiple others. Everything either doesn't do anything or sends the signal twice. I do a lot of watching
on it and this is a let down.

I am having the same problem but with Fios & Motorola cable box. Works fine until the system goes into standby. Next time we try to use the TV there is no signal and need to powercycle the XB to get it working. It's getting REALLY annoying.
