I have a URC MX-450 and an MX-850 and both have trouble with the Xfinity X1 box. Since the Comcast remote doesn't send IR, I can't learn the buttons from the original remote. I got close with the MX-850 software, but not all buttons are functioning correctly.

Is there a remote that works really well with the X1 box?

And is there a way to get a 30 second skip command?

Thanks!
