Both Stream website and app constantly buffering

I'm not sure what you guys have done to the backend of your streaming website and app, but for a while now, anytime I try to watch a show, whether it is live, recorded or on demand, it will constantly buffer and give the "Attempting to resume" message while trying to watch a show.

I have already cleared my cookies for the site, and logged back in, and still get the same issue.

Mind you, if I go directly to the network sites (using Xfinity as my cable provider at the prompt) and watch things there, whether live or on demand from them, I have no problems whatsoever.

What is going on?
