Just a heads up for people out there who are Comcast subscribers; (granted, some of this may sound like gibberish, so I'll use a picture to start to this off) -
Comcast has massively degraded picture quality in many markets nationally, and is about to do the same in Metro Detroit (they've already performed this in the city proper). Why you ask? Because they can, they think most people won't notice, and are shifting spectrum/bandwidth for more internet speed.
Here's a highly detailed explanation of what they've done - https://www.dslreports.com/forum/r31539495-
Some of you may have alternatives via at&t, Direct TV, Wide Open West, Dish, or one of the over the top (PS Vue, Sling TV, YouTube TV, etc.) TV service.
Comcast also recently instituted a 1024GB/month internet service usage cap.
I have no dog in this fight - I switched my folks over to WideOpenWest (no bandwidth caps, they still use MPEG-2 video and give the channels a good bitrate), and use a Slingbox to tune into a TV in the basement they no longer use.
Let me know if you have any additional questions - I am a huge nerd, and love talking about this stuff.
