Hello everyone. I recently purchased the antiquated DirectTV AM21 to coincide with the HR44. I live in the Baltimore/Washington area so I can receive from both markets. Since the AM21 has skyrocketed in price (200 + dollars) I thought my best option would be to purchase a used one from EBAY. I am now starting to wonder if my quest for a bargain was a failure. The OTA guide is stuck with California channels. I have spent the past several weeks troubleshooting and attempting numerous reboots with this unit but to no avail. The reboot I performed (which I discovered on another forum) was unplug and then plug in the unit twice which didn't work. I have also restarted the HR44 and during the restart process unplugged and plugged in the USB for the AM21. This has caused me a ton of frustration because I would like to utilize the AM21 OTA since it is integrated with the HR44 guide. Does anyone out there have any suggestions? The manual that came with the unit is useless as it does not provide anything insightful pertaining to this issue. Is there a way of clearing the unit and doing a fresh reboot? Any help would be greatly appreciated. Thanks.
