Screen freeze every 2 seconds with 2d message on cable box

Fixed my problem instantly I thought it was xfinitys doing... That Mac clear fixed it instantly! Thanks!

The MAC address solution has improved things for me as well. Has been saving me from having to restart the Xbox whenever I want to watch TV.

Not sure if it's a full, complete, fix but it's certainly better. Thanks for the suggestion!

@bionicgruen, thanks!!! My parents had this issue on BrightHouse with a Cisco 8742HDC and this immediately fixed it. I have no idea why a MAC address conflict could cause an issue with 3D/2D autodetection from the cable box but that worked : ) Clearing
the MAC settings must force some kind of hard interface reset on the Xbox One.

My dad was also able to temporarily fix this issue by power cycling the Cisco 8742HDC cable box, but he had to do that at least once a week.

I have this exact same situation but I am using a TiVo. No sound and the same pause cycle. I can also plug my TiVo irectly into the TV. I'm anxious for a resolution because I've beco,me a accustomed to the pass through functionality. Until this is resolved,
I cannot use LiveTV.

I am in the Xbox preview program. It appears they changed something with the last patch to my system..

Same issue with Time Warner and Cisco 8742HDC. Works fine after I reboot the Xbox though which rules out HDMI cable issues. I turn off my TV overnight and every morning I have to restart the Xbox in order to watch TV. I just tried putting the cable box
resolution at 720p instead of 1080i - maybe that will do the trick. The 2d switching back and forth could have to do with the Xbox not supporting 1080i. But then again something with the handshake resets after the reboot of the Xbox and everything works
as it should. I'm not sure if after idle time there is a time out and the handshake has to be re-established and it repeatedly fails? In summary, I have no idea what's going on or how to fix it. Fingers crossed on a fix from MS!
