Stuttering or Lag on certain channels

Over the last few months I have noticed that certain channels lag or stutter. Almost, like frames are dropping so movement isn't smooth. I have a X1 DVR box and two remote boxes. I don't notice it as much on the DVR box as I do on the Satellite boxes. Note, I don't see any pixelation or sound issues, just the stuttering of frame rates.

Things I have checked:

1. Called Comcast and had them run a signal test. Came back ok.
2. Ran both restarts and total resets from my local boxs
3. Used a process I found online to check the signals on the box and they seem in spec.
4. Channels that exhibit this behavior the most are the CW, Food Network, MTV.

Should I swap out all of the hardware, or call a tech out to check the signals within the house?

I'm in the Frederick, MD area if that helps.

Any advice is appreciated.
