On a side-note, our brave user (and now a contributor) Florian Steinel has got Rygel working with his PS3 already. According to him all his audio and image files are discovered and played/rendered without any problems but not all of his video files. Yes, there is still room for improvements but I was expecting quite a lot of work on making it work against a PS3 but glad to see that we are already very much compatible with it. Here are some screenshots of him playing with Rygel and PS3.
WARNING: If you want to try out Rygel with your PS3, you need to get tracker and vala from the SVN trunk.
UPDATE:Those weird looking titles in the screenshots turn out to be some Tracker-related issue:
<fsteinel> hhm, those name are already in the xml file lets see tracker...
<fsteinel> a tracker metadata bug nice, gstreamer gets it :-)
<fsteinel> gstreamer title: "El Reloj" -> tracker title: ÿþE
