I have a view scheme called Not Seen, for movies or tv shows that we have not watched yet (obviously).
My library includes a "Flag" custom delimited list which includes the value "Seen it"
My rule is as follows:
([Last Played]=>5y or -[Flag]="Seen it")
Last Seen is not in the last 5 years
Flag does not contain "Seen it" (I've also tried the Flag IS NOT "seen it" with the same result".
I keep getting files that I've watched 2 days ago. The file tags definitely show the files as having been seen:
Last Played: 2/5/2012 10:35 pm and the other shows Last Played 2/6/2012 10:28pm
