Video Errors with Verizon Fios - XL4
We've had our XL4 for about 2 months, first with RCN and now with Verizon FIOS.
With RCN our HD UI was a bit slugggish due to some higher RS Uncorrected and RS Corrected under the diagnostics screen (lots of wires in a multi-family). But there were no video problems.
Then we had lots of installation problems with FIOS in our new home. The techs were VERY anti-Tivo and wouldn't even check our signal at our Tivo location.
The RS Uncorrected and RS corrected initially were 10x worse going from 5,000s with RCN to 50,000s with FIOS and we are getting lots of video errors: pixelation, skips in live and recorded shows, sound cutting out, ect.
After 3 FIOS techs coming to our house the RSes are now down to the same levels we had with cable - but the video errors persist.
I've read that the FIOS signal can be a bit hot for the XL4s and some have suggested using attenuators. Our SNR is a bit high at 37-38, optimal being 34. So I tried a 3DB and then a 3+6DB attenuators and our SNR barely moved at all, still 36-37, mostly 37.
Have others experienced the same problems with FIOS? And how much DB in attenuators should I be trying to bring the signal down to Tivo range?
