Serious pixelation on Discovery Network channels

[poppiek6]

We've had pixelation problems on Discovery Network channels (HGTV, DIY, GAC, etc.) for over a month. Have checked all connections inside and outside of house, all were tight with no water in outside connection. Is this a network problem and is anyone working on correcting?

Are there any extra splitters that you can remove? Possibly May need a tech out to troubleshoot further. It’s not a network problem ;or you wouldn’t be the only posting about it

I have one 4 way splitter installed by Comcast a few years ago, fittings are tight. I live in a retirement community and I have one neighbor 2 blocks over having the same problem with the same channels.

Same issue here, so I would say it is a network problem.

It is just the Discovery network channels.

The main ones I am seeing the pixelation on are Discovery, Food, Travel, and TLC.

Some parts of the day it seems to be okay, but then it will drop out and be gone.

Not sure if it is related but the USA Network channel is now pixelated and drops out to give the message "This channel will be available shortly."
