I did not realize that X1 used MoCA between intra-home DVR's, so obviously no one should put one in-line with an X1 reciever. My apologies.   I had some errors creeping back in, so decided to look elsewhere for a problem, and I found it.   The access panel at my building was unlocked (I guess it's not a priority since cable theft via splitter is a thing of the past), and I found that my line had a splitter with an unconnected and unterminated port. Luckily I had a coupler on hand so I removed it.   I came back inside, rebooted router, and discovered the following:   Downstream signal levels on all channels increased from an average of -1.5 dBmV to 5 dBmV. That's significant because it's twice the increase normally seen when removing a 2-way split. There are a lot of nasty signal reflections going on in a splitter with an unterminated port.   Average SNR increased 5dB (from about 35 to 40 d .   Average upstream outpower decreased by about 5dB (from about 50dBmV to 45 dBmV). This is a good thing.   This isn't something most people should do themselves at an apartment building. You risk screwing up someone else's connection. At the same time, a tech should never leave an unneeded and unterminated splitter in place. Those guys do not have easy jobs with everything they have to deal with, but in my experience they always seem rushed and pressured to get to the next job, like everyone else who is working for a mega-corporation.   I welcome Comcast to look at my signal data before and after 6PM yesterday (2/7) if you would like to verify what I've said.   BTW - I'm not getting any "uncorrectables" since removing the splitter, and have removed the MoCA from the X1 line. There was one properly installed inside the access panel outside. ... View more
