You need to edit the theater view viewschemes, under options-->Theater View, and add your new "mike's movies" view.
Standard view and theater view have different view lists (by design), so changing your standard view options won't automatically change your theater view options.
Once you can see the view in theater view, you can focus on how to split the movies between the views.
Once under theater view in options and I click add I have several choices: Category, Root Library Item, Library Item, and Library Item From Standard View. I've toyed around with all of them but can't get it to list under Video?
Got it to finally not go under audio or in the root. So it is now under Videos and shows up in theater view under Video like I want but it already has movies in it and not just my movies? Not only that they are listed in categories: All Genres, Action, Action Adventure, Adventure.............
UPDATE
Fixed the way the movies show up. They are now by name. Had to manually add each what I'll call category under Mike's Movies. Now it all looks ok in Theater view on the tv BUT it shows all the general Movies from the Movies section in Mike's Movies.
I need those all to not show up and need to designate which ones show up under Mike's Movies. But don't know how to do that and don't want to screw things up again where I have to manually remove each of Mike's Movies from the general Movies category like I've already had to do. 342 movies is a pain. Not to mention I still don't have Mike's Movies in the main pane on the left under Videos in JRiver. I can manually add it again but I'm sure it will list all the movies again like it did in the past along with mucking up what shows up in Movies in Theater view adding in those 342 movies again.
So the new section Mike's Movies doesn't show up in the left pane under Video's where I can monitor it ie see which ones don't have covers and manually add covers etc.
In theater view Mike's Movies is showing everything that Movies has in it (both on my movies folder on the computer and what I have setup to show via the left pane under video/movies in jriver)
Those are the two problems I have left.
Just what I thought. I manually added Mikes Movies under Video (on the left pane of jriver) via right click and adding library view. Then proceeded to remove all the movies under Mikes Movies (because they were all the movies that are in the general Movies section) That removed all listing of movies from both Movies and Mike's Movies. So now no movies show up in either category.
Another update which has me stuck. Somehow the two categories (Movies/Mike's Movies) are tied into each other. I double clicked on the right pane while Mike's Movies was selected and imported all the movies in my Mike's Movies folder and it duplicated those added movies over into the Movies section also. Somehow I need to split these two categories so they are their own person independently.
