Your signal is too strong

WHAT?

I posted before about my Tivo pixelating and glitching. I called to see what the issue is and he said that my cable strength is too strong but he couldn't give me any recommendations.

Signal Strength: 100%
SNR: 39-40 dB
RS Uncorrected: 0
RS Corrected: 1099

What does this mean?

Thanks,

Dawn

PS: I have never had a Tivo rep that I didn't like but this one seemed be having a bad day or something. He wasn't the friendliest.
