Hi I have a problem with my box and I'm wondering if any one can help me.

Basically when I check the signal on the satellite and it is saying that the and AGC is at 15% and snr is 85% on tuner a and on tuner b AGC is at 54% but when I switch the cables around it says the same signal strength for each tuner.

When I connect a different box(mutant hd1200) to the cables the AGC is at 99% on both cables. I only check the signal because I and get 1second glitches and it was bugging me.

Thanks for any help
