I was totally surprised that with my WD LIVE I browsed through the Twonky Music folders and it did not present the correct sort order of my tracks - whereas the order is in the Tags as well as in the filenames!!
I checked the :9000 HTTP Media Browser - same thing!! Twonky Server (5.1 / Ubuntu) just ignores both filename and Track number ID when navigating through the tree. That is ... it DOES use them when browsing through Album, but who wants to browse through 1000 albums??? Browsing using the Folder tree is the only way guys, using the WD LIVE! And then, why not let the navigation be configured using the web front end??? This lack of functionality leads to an unusable product!
