But what would be special about the encoding on this one TV series that would make my receiver go nutty?

When such algorithms are used, they look for hints in the relationship bewteen the sound streams in the left and right channels, and sometimes end up with undesirable artifacts on audio sources which either were designed for alternative surround processing, or where they were designed as straight stereo. One example is very slight flanging of a channel between left and right channels, as might occur if there are two mics in a real environment with an assymetrically located speaker.
