Hello @jengle48, those pixelations are the worst, and they're a quick way to get annoyed, especially over your weekend. I'm sorry you had to deal with that, but I have your back on this. If you're still experiencing this issue, what troubleshooting steps have you taken to this point? That way we can try to avoid any repeated steps.

Notified:
My Comcast hasn't been the same since they advertised they were upgrading my service for 10G experience starting 8/25/23.
So far, upgrade has resulted in experiencing constant pixelation problems live and DVR, swapped both boxes, little difference.
Please be advised I only have a few months patience for this, and I'm a month in on this, before I consider alternatives.

Bringing customers like you the ultimate internet experience is our number one priority. That's why, in the coming days, we'll be making improvements to the Xfinity network in your neighborhood. The goal of the work is to enhance our network to ultimately allow us to deliver multigigabit upload and download speeds. This is just one example of how our next-generation Xfinity 10G Network is evolving to get smarter, faster, and more reliable.
Our most current information has us starting work on 08/25, affecting service at ***********. While we will make our best effort to stick to that date, sometimes factors beyond our control – like weather – may cause us to shift the schedule.
How this work will affect you
As our teams work to make these enhancements, you can expect service outages. This downtime will affect all of your Xfinity services, and if you are an Xfinity Voice customer, you will not be able to call 911 from your wired phone line. Please know our teams will work as efficiently as possible to limit the duration of these outages. We anticipate completing our work within the day. Continue reading to learn the best way to stay up to date.
Thank you for your patience

Replying to my previous post:
So, replaced the Comcast boxes, same result.
They were out putting in a new drop line on my neighbors service (needed to get to the telephone pole in my yard), explained the issue.
They had traced the problem to a defective card in the Bensalemn office and were going to be replacing it.
After replacing the service lines on my house and neighbors, both over 15 years old, they said they were getting a lot of noise on the line.
They were also putting filters on service lines to keep noise form getting back into their systems.
They replaced one old splitter and all the older hex crimp style connectors in the house.
Pixelization is gone.
Having a background in RF communication systems, I got some info and worked out the rest.
Long story short, years ago the occupied spectrum of the signal was about 1 GHz.
Now it's 2 GHz, 1 GHz for the TV and 1 GHz for the Internet.
Older splitters are only linear up to 1 GHz, non-linearites for signal components above that cause inter-modulation distortion products that appear as phase noise in the time domain on the signal at multiple frequencies.
Internet connection speeds previously showed good speeds, but probably only registered packets received .. not evaluating Bit Error Rates, etc, as it is functioning much better now with regard to page loading and VPN to work is much better.
