Wayne, you are a genius, and have the patience of a saint & the knowhow of Sheldon Cooper, (but definitely a much nicer/better personality)
So, In re;;;;;;;;me and the Previews.....Once upon a time, I was able, via a big sattelite dish, to get Days as it was fed to a Canadian station at 3 a.m. A day ahead of when U.S. stations got it. That was such a great time, On Fri. morning, I not only had already seen the Friday cliffhanger, but the Monday followup as well. Alas, eventually, the Days' suits decided Canada should be same day, & eventually the bonanza came to an end. Canada no longer aired any sort of Day Ahead, my receiver died, and now I moved away, living in the town now.
So, yes, the Preview is no longer valid, perhaps could just be attached some way to "Days in the Past?"
