The system wasn't designed for non jukebox activities. So if you set up for jukebox..you would only have fanart in folders containing the muisc..becuase the other levels are just storage structure.
what haapens if you only have fanart in the diks1/disk2 folders using jukebox?
As stated above, in jukebox mode fanart is not displayed either, though system doesn't crash.
And again, whether by design or not, the feature works perfect up to three levels deep (music/artist/album).
Another thought, if it is not related to the folder structure, could it be the fact that my music collection is perhaps above average size? (15000+ tracks / 1200+ album in FLAC format, 1.5 TB in total).
My best attempt to explain the structure of my network. In below example album 1 works as it is supposed to and album 2/disk 1 crashes the system the moment I start playing track3:
-- Artist1 folder
-- album1 folder
-- album2 folder
-- disk folder
