Ok. I installed your app on another device (S4 Mini). The playback from my Twonky server worked fine. Yet there is another problem. The songs are listed alphabetically. They play not in the correct order.
I have upgraded to the full version and it works. Unfortunately I cannot access any SMB-shares on my local network, so I have to transfer all media to each player (but I have two or more players). Will you implement SMB/CIFS-Support for direct network file acess?
PS: I also have DLNA issues (D-Link DNS 320) and therefore I prefer SMB over UPNP/DLAN.
