When looking at various UPnP media servers, one of the features I wanted was the ability to play back my music collection through my PlayStation 3. The complicating factor is that most of my collection is encoded in Vorbis format, which is not yet supported by the PS3 (at this point, it doesn't seem likely that it ever will). Both MediaTomb and Rygel could handle this to an extent, transcoding the audio to raw LPCM data to send over the network.

One of the nice features of the PlayStation 3 is the UPNP/DLNA media renderer. Unfortunately, the set of codecs is pretty limited, which is a problem since most of my music is encoded as Vorbis. MediaTomb was suggested to me as a server that could transcode the files to a format the PS3 could understand. Unfortunately, I didn’t have much luck with the version included with Ubuntu 8.10 (Intrepid), and after a bit of investigation it seems that there isn’t a released version of MediaTomb that can send PCM audio to the PS3.
