For albums like this, you need SOMETHING that differentiates them. Think if you were telling someone to go play that album for you and to go find it on your CD shelf. They would tell you they found 2 that have the same title and the same album artist. Which one do you want them to play?
The answer might be "the one with the blue cover". Or the one published by (whatever the publisher name is). Something that you recognize has to differentiate these albums.
I would suggest that this differentiating factor be part of the album name. This makes it very easy; everything just works from there. But if that's not something you want to do, you can do it the hard way.
In two of my Album views, I have the Albums grouped such that it takes the file format into account. So I can have an album in FLAC and the exact same album in MP3, and it shows them to me as separate albums. I do this by defining the Album field (inside the view) as an expression. I use this expression to group them:
[Album Artist (auto)] [Album] [Album_info][File Type]
That [Album_info] field is a custom field I defined. I use it to differentiate albums that have the same album artist and album name. For example, I have Fleetwood Mac's Rumours album in both CD and DVD-A form. The [album_info] field holds this extra information and my view uses it to group the albums.
This all works great if you ONLY USE YOUR OWN VIEWS. As soon as you use stock views, or JRemote, or Theater View, it no longer works. You have to redefine every view that you want to use these grouping rules.
That's why I called it "the hard way". It's a lot of work and you need to figure out every single place that uses Album that you care about and change it.
For that reason I gave up on this a while back and just change album names to reflect this extra information.
BTW, if you still want to do it the hard way AND you just want to use your folder name, you can make your expression use the parent folder name to group by with an expression similar to mine, but using that parent folder expression. I'll leave the details of that to you or someone else that wants to mess with expressions today.
Best of luck to you,
Brian.
