Please try this module and report if something is missing. After verifying that everything is working well, it will be easy to create the TwonkyMusic module too.
P.S. IMHO this too is a very nice DLNA UPnP Media Server with a sophisticated and rich set of features and administration interface (from what I can say after testing it for a short time). After now testing several other Media Servers and due to the fact that this is the first time I'm playing it, I get the impression that the choice for the Mediabolic DLNA server was not the best one.....
Have already installed it, configured it and now in the process of uploading files (via NFS from the file server i used till now) - this takes some time (about 400GB). The installation was without any problems and the configuration pages of Twonkymedia were accessable after enabling the module.
Think life of my old file server is finished soon.
