This is how up next handle the FBI shows ....
First on the list to be played was ... FBI International which was really part 3 of a crossover .. Nothing else showed up of the FBI Shows they were buried. Nothing like watching Part 3 and have no Idea what is going on. Upnext should show new shows by Airing time. UP Next is so darn Random.
Recently added is not much better.
In SageTV I could sort by recorded date/Time ascending unwatched.
I find recently added to be more useful at least I can start from the bottom up when watching new shows.
