So... I've been doing some thinking about the track scanning problem. The dozen or so tracks in that directory aren't the only ones not scanned... but I'm thinking that figuring out a list of tracks not scanned will vastly help.
To that end: a database dump (possibly in XML format, or whatever you like) would be most useful to a lot of people and most helpful to me. I read that you have a dump to itunes somewhere --- and I can't find where that file ends up. It says the caveat is that multiple tag values are not supported. I would like, say, a similar XML dump with all tags included. This would allow me to compare my list of files with the ones that the library has ingested and find the culprits.
