I have recently purchased a Sony BDP S390 DLNA blu-ray player. I have a Twonky Linux server. If I browse to my Twonky server on the menu on the blu-ray player it shows all of my mp3 files, but when I try to play one of these I get a message "File format not supported".
I can play mp3 files on other devices - eg an Android phone and tablet, and a Denon ADS-3W DLNA iPod dock.
How can I get mp3s to play on this device?
