I figure I'll update this thread, even though I never figured out what the problem was. I ended up just using mp3 instead of ogg, which is a much faster DB build. I currently use mp3 320 ABR files with id3v1/id3v2.3 UTF-16 for compatibility's sake (though v2.4 is faster).
I've managed to avoid the OF refreshes entirely by using the trick I detail here
, so I only have Rockbox's painless auto-update worrying about the database.
Anyway, consider this problem not solved, but worked-around; though if anyone has anymore insight, I'm sure ogg fans will appreciate it.
