When I scan in the radio channels on AMC8 and go to the "function: browse" menu the receiver locks up. When this happens the video becomes distorted and the graphics unreadable. Also, if I hit "OK" to bring up the channel list and attempt to scroll up or down it the receiver locks up after moving one channel. The video does not become distorted when this happens. I have tried the following in an attempt to clear this up: 1) Deleted all radio channels and re-scanned them 2) Did a Factory Re-set 3) Deleted all TV and Radio Channels and did a Factory Re-set 4) Re-entered each Radio FR and SR one at a time and deleted them one at a time to see if one of them was the problem causer None of these steps cured the problem. Does anyone know what is causing this and how to cure it? I have also discovered that I can go to other satellites and scan in radio channels and everything works properly. This just happens on AMC8.
