Hi,
I am an RCN user. I have a Tivo Premiere Quad and a Tivo Preview.
I recently replaced my cable modem with a Motorola Surfboard -sbg6782 (integrated router, wireless AC, and MoCA). It works well for all these functions.
Since installing this device I've noticed some weird/distortion/pixellation effects on recordings certain channels. It's not quite pixellation-every 5-10 minutes certain blocks get kind of distorted/fuzzy.
Right now there is a powered splitter outside the house that splits the signal two ways, one going downstairs to the Preview and Cable/Modem and the other going upstairs to the recording Tivo. The Preview uses its Ethernet interface to connect to the MoCA adapter in the basement and the Tivo Premiere connects via its built-in MoCA to the network in the basement.
As far as I can tell there are three possibilities.
1. The new cable modem, in its capacity as a cable modem, is doing something to interfere with the cable TV video signal.
2. The new cable modem, in its capacity as a MoCA adapter, is doing something to interfere with the cable TV video signal.
3. Having changed/simplified my splitter arrangement in the basement to work with the cable modem instead of a separate MoCA adapter, I've changed the impedance of the system causing the signal to come in too strong/weak upstairs.
It is hard to diagnose because it's not continuous-it's every 5 or ten minutes. Any suggestions for fixes, or even how to isolate/target the problem would be greatly appreciated.
