TV shows freeze, pause and then continue

I am writing as I am having issues with my Comcast service.  I have three TV's and three Comcast TV boxes.  I have the X1 Gateway.  

For the past few months, the shows that I watch, pause or freeze and then after some time, they continue.  The freezing or pausing can last just a few seconds or can last for several minutes.  It makes no difference if the show is something I am watching live or something I have recorded.  

I've seen quite a few complaints here going back a few years so I know this is a Comcast issue and something that is ongoing.  How can I resolve this issue?  Comcast charges too much money for this kind of thing to be happening.
