Try hiding the Streaming Channels under Settings/TV Inputs/Manage Channels/Hide Streaming Channels.
Then do a reboot of the RokuTV from Settings/System/Power/System Restart.
After the RokuTV reboots, select/launch the Antenna TV icon from the Home Screen. (Do not use the LiveTV from the left side Menu.)
After AntennaTV launches, use the left arrow button on remote to bring up Guide. (Otherwise just use up and down arrows to channel up or down).
