I am having the same problem. When I'm watching online, I get as far as the first commercial break and they I get either unlimited commercials (the same 5 over and over and over again and I have timed it for 30 minutes then finally shut it off) or a couple runs of the commercials then a mostly black screen with a note that it is "buffering" but the show never comes back on.
I haven't been able to finish a show in WEEKS!
I contacted comcast and they said it's the channel that controls the commercials...but it happens whether I'm watching FX, ABC, CBS, or AMC.
Does ANYONE have a suggestion? I'm not going to be able to get caught up before the shows start falling off the playlist! Ack!
