OK... just figured out my problem. Looked at the back of the unit and noticed the Ethernet cable was not plugged in. We had the Comcast guy come out to look at our service and he unwired everything and I guess he missed connecting the replay unit back in. Here's the thing though. Because the Replay unit downloads days of program scheduling in advance, we didn't notice the problem until the stored data ran out. So... I plugged in the cable and viola! back in service. Regardless... this forum is an excellent place to find answers.
