[QUOTE="spiney, post: 143146, member: 192438"] Well, "blocking" (picture breaking up into square) is pretty certainly due to poor - not necessarily low strength - signal and nothing else. Note that, when you look at "signal quality", it's for default transponder (epg one, I think!). If blocking only on some channels, then you have to look at those, which means getting the particular details (via websites), and entering into "manual tune" in special installer menu, then you get a quality reading for that one (as Rolf says!). Could well be from other stuff, some mobile phone systems transmit within the sat i.f. band (from lnb into receiver), can't remember dect frequencies (2.4 ghz?) and would only affect some channels. However, there's various other possible interference, beats harmonics, etc. Shimmering puzzling, can you describe further? [/QUOTE]
