So I have some playlists based upon frame width, as an example, to determine which movies are SD movies (frame width less than 700px).

I have replaced some of those movies with their 1080p counterparts, however, the playlist based on on the above, does not purge out the old entry from the custom playlist based on size. If I manually delete the file from the playlist, it goes away, however, if I delete one that is supposed to be there, and then re-run maintenance, it doesn't add it back to the playlist, so I suspect that there is something going on.

Is there another scan that I need to be doing to re-populate the playlist correctly?

Thank you.
