It does. Your second example, in quotes below, will yield a situation in 'all movies view' like this-
Dark knight Collection- folder.jpg < this will display the collection image and when you click on it open to the three actual movies with .TAG files as long as, like you say, the .TAG does not have an image embedded. The problem with this though, is that the three movies will be displayed as generic Netgear icons since there is no image file for it to read.
To get the images or 'cover art' to extend into the 'The Dark Knight Collection' folder you need to add an image file for each movie, but instead of naming it folder.jpg the image file will need to match the .iso file name. So 'Batman Begins.ISO' will need a 'Batmanbegins.jpg'
In short- the folder structure with folder.jpg 6 is the way to organize movies so the Negear displays 'all movies' view and box sets correctly.
The trick is now figuring out how to work with MCM to make this happen.

As you said - the dev over there is really responsive and has already asked that I submit a ticket.
'If you want them to all to be depicted by a single image then use a folder.jpg file and don't have the image embedded in the .tag or a movie.jpg file at all.'
