Now that we're getting afternoon storms here in Atlanta I've noticed a problem that seems to mostly just affect the mpeg4 channels. Whenever it's about to rain, even if it's just cloudy, these channels all go out. The mpeg2 channels work almost 100% of the time when it's raining. I've looked at the signal strength of all the satellites, but I'm not sure which transponders I need to be looking at on the non 110/119 satellites. Most of the strengths are extremely low, but I'm not sure which ones are used for national HD and which ones are spotbeams. Is there a list of this somewhere?
