I have been reading that there isn't such a thing as too high a SNR... I am getting V53 errors on random channels at random times. My signal strength is in the low 90's and my SNR is between 37-40. Tivo is telling me that the SNR is too high, and that I need to have Charter come out and fix it. They have come out several times because of intermittent internet (I think caused by the same problem) and they never fix it. I am not sure what to do here if Charter won't/can't fix it. Tivo will not accept my Roamio as a return since its been more than 30 days. Also - I have tried using various attenuators and they will not bring the SNR down. Please help!
