I use this basic expression in Theatre View.
'[Media Type]=[Video] [Media Sub Type]=[Movie] [Last Played]=never played'
It works but it typically gets converted to...
'[Media Type]=[Video] [Media Sub Type]=[Movie] [Last Played]=never playe'
with the 'd 'from 'played' being added to a Custom box or truncated to 'playe' after saving. I'm guessing this is normal? Is there a character limitation at work here, or am I misusing the [Last Played] field?
