I have a number of smartlists created that filters the number of plays for a particular set of video files. When the number of plays is less than 1 the file(s) in a set are visible in the smartlist. When I've watched a file it will disappear from the playlist set indicting I watched it. This has been working great with Media Center versions 13 - 15. With the start of version 16 and now 17 there is, we'll say, at least an hour delay as opposed to no delay, when it was working correctly, for the smartlist to update based on its filter specification. Now when I watch a video in a smartlist it remains there for quite a while unless I exit Theater View, select the smartlist, hit the refresh button then reenter Theater View and the recently watched video is now filtered from the smartlist.
