I am posting this as a new thread to help others. Posted this 8/25/2012: I called DirecTV again today on this issue and they said they were aware of the video drops but also several other issues: 1) video stops while audio continues. Timed at 6 to 40 seconds. 2) remote fails to control the receiver even while the blue light on set indicates a valid signal - happens for moments to a few minutes. 3) while #2 occurs, the navigation buttons on the set are also inop. 4) audio stops completely while video works and channel changes are ok. Again moments to a few minutes. The response from DirecTV is that they will not replace these receivers since the problems are known (I have the equipment protection plan); they are not offering any idea as to a schedule for a fix; they are supposing that these are software problems; they will not discuss a receiver upgrade unless associated with a national/regional upgrade plan. Perhaps if more of us call and complain, this might lead to a fix. As it is, I have been with them for over 10 years and they don't seem to consider a potential loss of my account as of particular interest. I have grown to like the channel lineups offered, and the service used to be great.
