Maybe this was a fluke thing, but I'm not going to try to recreate it, since I've already lost one show I hadn't watched yet. I used '--' to delete the oldest episode of a show with 2 episodes saved. Rather than deleting that show, it deleted the show next in the list, of which there was a single episode. I'm positive I had the right show selected. Like I said, this may not happen all the time, but it can happen. From now on, I'll be doing deletions the "hard way" just to be sure it deletes the right thing (doing it that way worked).
Sigh. Yet another show we need to find some other way. Not the end of the world, but a pain in the rear...
