Sunday night I lost my HD locals on my HR20-700. The SD versions were there, as were all the other HD channels. I know there were there at 4 pm, as I had the Redskins game recorded on it. I called DirecTV and went through the whole reboot/unplug checklist. Finally we were about to schedule a service call when I got disconnected. I let it go and decided to see what happens - I have an OTA antenna and an HD TiVo, so I'm still covered. Monday, the locals were back. Weird. Then Monday night they were gone again. Occasionally the unit will start to show a picture, but it will immediately pixellate and freeze. I'm thinking this is a dish alignment issue. We've had some decent winds lately, so maybe it was barely in alignment before and now it's barely out of alignment for that sat. Agreed?
