I have been getting 771 errors on my HDDVR on different HD channels. Most notably, the HD channel that I watch the most often (647-1 FSNHD) rarely comes in anymore since the latest update. Another channel that I have tested that gets the 771 error is Weather Channel HD 362. I have tested on my H20 HD receiver when this happens and it receives the channels fine. But my HR20-100 won't get the channels. When I go into the satellite setup and check the signal strength everything is fine except for 103(c). Tuner 1 has a good signal, but tuner 2 has no signal. So I call DirecTV and they want to send a tech out even though I told them everything was working fine before the most recent software update and that I was pretty sure the issue was with the new update. So the tech comes out and does the following things: 1. Replace my HR20-100 with a HR21-200. 2. Replace both B-Band convertors. 3. Replace coax connector cables. 4. Replace the switch. 5. Test all connections to switch. 6. Make sure everything is grounded properly. 7. Reboot both receivers and rerun satellite setup. 8. Switched cables to the tuners. 9. Realigned and replaced LNB's. In the case of the HR20, tuner 2 was always no signal on the 103c satellite. When we plugged the HR21 in it worked fine with good signal on everything. We then rebooted it and got the newest update and tuner 1 had no signal on the 103c satellite. We came to the conclusion that the issue has to be the update that was sent out. What am I supposed to do? I am sitting here tonight watching the Cardinals in SD because the HD channel has a 771 error. I am mainly paying for the HD package so I can get FSNHD, yet I can't receive it since the update. Is my only option to wait until the next update and hope that it fixes the issue? Should I call DirecTV and demand a credit for my monthly HD fee until they get an update that fixes the problem? Why would only 1 tuner be working on 103c? Which channels are received from 103c? I'm assuming at least Weather Channel HD and FSNHD are received from this satellite and that is why I'm not receiving them. Also, on top of the 771 errors I have been getting recordings that won't play and my receiver won't turn on unless I reboot it. What are my options?
