I'm having a problem with my 322. I'll be watching for about 15-20 min when the picture disappears with vertical lines. I can hear the audio but there is a loud screeching sound. I disconnect power and reset the receiver and everything is fine.....for 15-20 min then it starts all over again. My entire system is new (installed yesterday!) I've got an 811 fed straight back to the LNB , then I have a sw34 feeding a 322 and 2-311's. The 322 is the only receiver screwing up.
