What about disabling LNB Feeding Voltage, wouldn´t it help out? My standalone receiver stays remarkably colder with LNB Power off.(QuattroLNB, 1 Analog & 2 Digi receivers, Analog feeds LNB, Digis LNB power off) Might help with 1+n cards... Isn´t it possible to feed the LNB by an external Power Supply? regards Thorsten
