I wonder if anyone else have experience a similar issue. The programming guide will not show up on the screen when clicking on the guide button, the picture-in-picture (PIP) to the left bottom screen will be he only thing showing as if the DVR was unable to render the programming guide grid on the screen. In fact, even the recorded shows menu/list will not show as well. The only thing showing was the PIP to the left bottom screen. I called in ATT tech support many times on the issue and the standard procedure was to reboot the DVR which fixes the problem. It becoming very annoying lately since it keep happening almost every 2-3 days and I had to reboot the DVR every time. Has anyone experience similar issue and what have you done to clear the problem?

Thanks
