Poltergeist: The Legacy

I've been following the episodes on Chiller and noticed that the one I'm watching now "Infernal Affairs" isn't listed as an episode. In fact none of the ones that have been on since the showing of "Sabbath's End" are listed. Tomorrow the episode is "The Beast Within" so I guess the series is back on track, but where did these additional shows come from? I've done some additional searching online, but haven't found anything about them. The one today is nothing special because it's just clips from previous shows put together around some loose plot to form a show. I figure this is just a way to get a program when the writer's are lost for a new idea.
