Last week's episode of "Fear the Walking Dead" as aired in my area (Lafayette, IN) was missing key scenes because about two minutes after each commercial break was over, Xfinity dropped in a minute of local commercials- obliterating the show that was supposed to be on. This is absolutely not acceptable in any universe. Worse though, is that there doesn't seem to be anywhere to report this sort of thing. The new local channels have been doing stuff like this to themselves, but I expect better from Xfinity, and I imagine AMC does too.
They seem to have timing issues with their insert commercials. When watching "Drunk History", the last commercial break runs over by about 30-60 seconds due to a local insert. It has been doing that for several weeks.
I've seen overruns too, but that's not what I was posting about. This is a separate batch of commercials shown after the show starts up again- which is even worse.
