Recently had to have my dish moved from the roof to my porch due to new rules in complex. In doing so the tech switched my satellite dish to a newer one. Everything is fine except I'm missing some corresponding SD channels, for example USA only comes in HD. That's fine when I'm watching it, but I prefer recording in SD to save room. Some are coming in both (HSN for example) but others are just in HD. Any ideas? Checked and I get both satellite 72 and 61.5 and both tested okay.
