Okay... I can see immediately that what you are trying to do won't work. First off, reset the views twice so that you are starting with a known-working starting position.
Now, select the stock Video view. See how it says Type = Secondary roller? That should really be relabeled "Show Child Views as" rather than "Type" because that's what it does. It chooses how the views on the next level down work. These new "Secondary Roller" views (the ones under Video in the default Theater View setup) should not be imported from Standard View. They can't contain "categories" (the fields shown in the Details section of the Theater View setup dialog), as you can see because that panel isn't even shown (you just get the "Set rules" button but no list control to add the fields). With a "Show Child Views/Type" parent view set to Secondary Roller, you effectively MUST have three "levels" of views. The "middle" view (the one that appears on the secondary roller) should contain ONLY filters that determine what files are viewable by child views. Any sorting you apply here is ignored. If you import views from Standard View here, they seem to come in half-way baked (if you actually take them and re-nest them up a level, they become fully functional again, so those categories they contain are actually preserved, but broken).
So... The way this will work is to do it like this:
1. Select Video in the Theater View setup panel.
2. Click the Add button and choose Library Item. This will create a new view just above the Video view (annoying).
3. Select this new view, and click Move Down, then Nest. Then you have to manually move it back up above all of the stock stuff to get it where you want it (also annoying and fiddly).
4. Select this new view, and rename it "TV Shows" if that's what you want it called.
5. Click Set Rules for file display and add any filters you want. This will probably be simply [Media Type]=Video and then [Media Sub Type]=TV Shows, This will work if you want it to only show files manually tagged as such. If you want it to use the new "Smart Logic" (which can actually work well in some circumstances), then you use this instead (enter it from the Import/Export dialog): [=MediaSubType()]=[TV Show]
6. Now, select TV Shows in the list (if it isn't already) and click the Add button again. Now, you can bring in a view from Standard View here. So, find and choose your TV Shows view.
7. I'd recommend against calling it the same thing. The new Theater View system seems to not like it when you have two views called the same exact thing. I called mine "Series". When you add two views with the identical name, they get messed up (at least in my testing it appears to work that way). It is even possible that it'll get messed up if they are called the same thing even for a minute, so you might have to name your view created in step 2 something else temporarily until you can get this imported one renamed. This is what causes the "blank lines" issue you're seeing. I reported it in the beta thread, but no one responded.
8. Now, open the Set rules button. You don't need all of the filters, because you already have them in the parent view and they're inherited, so remove them all. You can use the "Modify Results" section here though, so you can add sorting rules.
If you follow this, it should work.
Now, the nice thing about the new system is that you can have more than one TV Shows view, and quick switch between them. I have one configured basically just like I described above, but I then added a second view next to "Series" called "New Shows" which uses the same filters (so it shows only TV Shows), but which has no fields added to the Details section, and which sorts the newest stuff to the top (and is in List view mode). Now, I can select "TV Shows" from the front page, and it'll open and show my Series view. But if I just want to quickly get to something that JUST AIRED, I can jump up to the secondary roller and switch over to the "New Shows" view and there is all my new stuff. I like to use the [=MediaSubType()]=[TV Show] for this one, because then it'll show things that I haven't even tagged yet too (though then you can't add the filter to the "TV Shows" view in the step above).
