Okay, here's another bit of expression fun I've been mulling over for some time.
I'd like to make a search that returns all of the episodes of any [Series] where we've watched some episode of said series sometime in the last, say, 2 months. I'd then filter out any episodes we've already watched (ideally using the Watched(1)=2 mode, but that doesn't work right, so I'm probably going to have to craft my own method to generate the same result).
That way, I could have an "Active Shows" view in Theater View, which would list only waiting-to-be-watched episodes of shows that we're "actively watching". Even though I archive out (or delete) shows after we've watched them and we've finished a particular season, we often have a large pile of shows that the PVR is recording but which we haven't started yet (it is a rare show that we watch as they air, or even within the same week or so). So, my regular All Series view is filled with a bunch of stuff we're not likely to choose in those situations.
This view would be super convenient, and I hope there is a way. I just don't know how to pull all of the episodes of a particular show if any one of them has been watched in the given timeframe. It would be similar in practice to pulling all tracks from an Album where any one track in the album had been listened to in X weeks, or was Rated above X, or whatever.
