Click the 'Import/Export' button at the bottom of the search wizard and enter the text. You can't use the friendly wizard controls for these special rules.
This didnt work. It produced the rule set as in attached picture. I had also previously experimented with this when using the standard wizard to produce the same rule set.
However, it works for unest and moving up or down, but not when
renested under my parent item that had rules , media type=video, subtype=TV Show.I didnt expect that would be a problem but perhaps it isnt classified as "video" or "tv show" until
after it has been recorded ?
At any rate renesting it under a 'dummy' library item without any parent rules also works.So problem solved if I now use a parent item without rules and only place child objects with all their rules included.
For others reading, I found using the Import/export method a bit confusing as I was not actually importing anything. Pasting Matt's line of code [TVTime]=>#TVGuideStartDate [=TVInfo(Record)]=[1] ~d=g after opening the import/export dialogue of course works,thanks Matt. I'm guessing the ~d=g adds the modifier "Limit database to tv guide".
Thanks again
