I have the Motorola DCT3416 HDPVR. Today, I have completely lost all of the my PVR capabilities, for no known reason. I can't access the guide, previously recorded programs, or modify any settings, such as the clock, which is how I discovered it wasn't working properly. When I attempt to access PVR capabilities, I get a message stating: "DVR service is not available or is disabled. Call your cable operator." I have turned off/on, unplugged, and even used a different outlet. HELP!!!??? I am extremely frustrated!
