Just got switched from Dish over to Direct TV. Have the HR-23 and Slimline 5. Installer could not get a signal from 99 and 103. So, no HD. He could not get it dialed in and will have to get another installer to come out and help. I am stuck looking at SD channels that are very pixelated and some audio stutter. My question is it looked like the other satellites are around 100% signal strength. Does it sound like a signal strength issue? Installer did not seem to knowledgeable so I need some advise. I hope this is not what I have to look forward to on SD channels. Thanks!
