MLB "stop action" problem

Is anyone else having this problem with MLB. The picture pauses then jumps ahead. The sound is perfectly fine, so I’m pretty sure it is not a DL problem with Comcast. Also I don’t have this problem with anything else. I do get stoppage when the screen goes blank and you see a downloading bar, but this is completely different.

It started during Spring Training, but I thought maybe they just didn’t have as much band width or something at those parks. But it is continuing into the season and it is most annoying.
