Quartet, a movie on Movie Central Ch. 60, was almost over this morning so I checked Other Showtimes. The only other time given was "yesterday, Movie Central, Ch. 60 at 6:20 pm". I've seen "yesterday" given before as an alternate showtime and thought it was just a holiday glitch so didn't report it. Today however I decided to record the yesterday time given and sure enough it recorded! I then went to Scheduled programs and found the movie not in a "yesterday" time but set to record on Tuesday Dec. 31, Ch. 60 at 6:20 pm. This Tuesday time was not given as an option when I checked Other showtimes.
This might be something you want to check into. It doesn't happen all the time but I've seen it maybe 6 times. It can't just be happening to me.
