we’ve had Comcast forever and just upgraded to X1. Channels 850-853 are tiling. Unwatchable. After going round and round with customer service rebooting the box multiple times, a service call was finally scheduled for a few days from now. I’ve always had an issue with the “live” sports channels. I thought X1 would fix this. Any ideas or alternate channels for NESN? I’m in Manchester, NH.
