I currently have 6 HR-2x and one HR-34, which is a total of 17 tuners. I have had it set so that one receiver had one one tuner enabled. But in the past few days, we keep getting 771b errors on the HR-34. It appears that somewhere along the line, I have now lost the ability to completely disable that second tuner, perhaps through a recent firmware change? So, I was considering moving that receiver to the legacy port on my SWM-16. But will that pass DECA?
