Yet another TV Guide Network mystery. Since yesterday afternoon the TV Guide Network on my Xfinity System in Bristol, Connecticut (Channels 72 and 100) has been showing the listings for COX Cable of Tulsa, Oklahoma. And if that part weren't strange enough, the times on the screen are the normal Eastern Time Zone times and not Central Time Zone like Tulsa is. Is Tulsa, Oklahoma the default mode for the TV Guide Network if the local listings crash?
