Multi Disc BR ISO's showing up as separate movies

[jkasanic 12]

I tried searching for an answer to this but most of the information on multi disc files is from late 2014 or early 2015 and predates "Collections" (which I'd prefer not to use in the case of a single title multi-disc movie) and I did read the Wiki on file naming conventions.

 

I have several multi disc files that are correctly being recognized by Emby as a single title and including the 2nd disc as an Additional Part.  For the most part, these are mkv and DVD (VIDEO_TS) files.  One movie in particular (2-Disc 3D ISO's for The Hobbit: An Unexpected Journey) refuses to add the 2nd disc as an Additional Part no matter what combination of filename convention, nfo file format etc I use.  I don't believe it's a naming convention issue since other file formats are working correctly but for the sake of clarity, here's how I have my files setup:

 

\media\moviename\moviename.disc1\moviename.disc1.3D-MVC.iso

\media\moviename\moviename.disc2\moviename.disc2.3D-MVC.iso

 

Where \moviename is the same directory.  I've also got nfo's in each disc folder with the following information:

<movie>
    <title>moviename Disc #</title>
    <id>imdbid</id>
    <sets>
        <set>moviename</set>
    </sets>
</movie>

The nfo appears to be setting the "moviename" correctly because in the web browser I can see the "Disc #" at the end of each file name.  Is it possible that ISO's are handled differently than mkv or DVD structure?

Hi, it's the extra disc sub-folder that I think is causing this.

So you're saying I should just have both movies in the same subfolder?  That's fine (and I'll try it this way for The Hobbit) but I guess I'm wondering why it's working on the other file formats that all have the same subfolder structure?

the sub-folders i'm pretty sure are only supported for folder rip structures like dvd and bluray

Ah ok, so works for BDMV folder structure but not ISO.  That makes sense.  Thanks for the response!
