I have gotten a new 811, it seems to look never used, still has plastic on front window, super clean. I want to see about using for OTA stuff. I read you need sat dish attached for anything to work. I aimed the dish properly so it could get a signal and it never leaves "searching for information" message window. The sw ver is P051LABD-N, bootstrap 1-1-LABD, card rev 281. Is there anything I can do to get out of downloading vital info forever? Is this nice HD receiver pretty much useless, which is why it was tossed in the first place?
