I have a playlist I created in NSM which shows tracks in a certain order. However, when I transfer the playlist to my Neuros, it moves some of the tracks around! I don't want my DAC re-ordering my playlists because it screws up my audiobooks! How can I make the DAC respect the original playlist order?

?
Tracks are added and sorted by directory, where the directory structure looks like this:
disc1\track1
disc1\track2
disc1\track3
disc2\track1
disc2\track2
etc., except there are 20 tracks on each of 20 discs.
Thanks!
