Xfinity Stream unwatchable

I have tried about a dozen shows, a few movies and they all do the same thing. I start up the video, and instantly the video fragmentizes and half the video is chopped up and out of sync. Audio works fine. This appears to be on the back end(as in service side, not on my end.) I have tried several other services(hulu, amazon prime video, netflix). I am curious when ill be able to watch my content again? I pay for a service I expect to utitlize  and have until yesterday.
