if i have all 6 tuners on the 6th tuner is left with no sat signal? i can make this "hop" between tuners. ie shutting off 2 switching the one with no signal on then turning on what was say the 5th tuner now that one has no signal.. hopper or joey doesn't matter. is this normal.? i thought that at least it should be able to mirror one of the other tuners or access one of the dvr's but that isn't an option. it only pulls up the acquiring signal screen or if i bounce around with guide and cancel buttons i can get red button to pull up usage screen and it shows other devices being used but that tuner i am on shows signal loss ?? i have had service for 2 weeks now. any info would be appreciated. thanks
