When my receivers have to re-aquire the sat signal, I have always been able to trace it to:

- Windy weather... either blowing my dish or blowing tree limbs into the signal path.

- Cloudy skies. Depending on where you are located, a cloud system several miles south of you but not overhead could be the culprit.

- when DirecTV is showing several Dolby Digital movies, which tie up more bandwith, and let the signal hold less data with each aquisition. They've been doing this more and more recently. Personally, since I bought a Digital receiver, I'd rather have more Digital 5.1 movies than fluent guide access.
