If I have live TV on the same channel on 2 different TVs....there is about a 15 second lag from the TV with the X1 DVR vs the TV with the smaller box.
Is it just a limitation of the X1 platform?
I have super fast internet and have the boxes hooked up via ethernet cables.
Yes I have seen that also and I am not aware of any way to sync them other then to run both TV's off of one box. This is not just a comcast issue as I have seen the same issue on two other cable providers. If someone know of a solution I would love to hear it also.
