Yes, that would be my preference for root schemes in Theater View (for me, the actual Theater View is not relevant, but the TiVo view is). For example, right now my audio root scheme is set up as:
Album Artist (Auto) [groups of 2]
Album Artist (Auto)
Album
If I have other view schemes set up to show in Theater View (e.g., Genre/Artist/Album, Compilations), what I see when I open the Audio folder in TiVo is:
Genre/Artist/Album
Compilations
0-9
A-B
C-D
E-F
...
etc.
Unfortunately, this means that there's no label to give the user an indication of what the 0-9, A-B, C-D, etc. groupings are (album, artist, genre, name?). It would be preferable to see:
Artist/Album (the name of the root view scheme)
Genre/Artist/Album
Compliations
...
etc
Then the user only sees the 0-9, A-B, C-D folders after opening the Artist/Album folder and understands that these groupings are by Artist name.
If the above is not possible, then I would at least suggest diabling the option to "Show in Theater View" when editing the root view scheme.
