I installed Mediatomb on my new FreeNAS box, and it's working really nice. FreeNAS includes Fuppes UPnP media server, but I didn't care for it and had problems getting it to serve some video file formats. Fuppes is all about re-encoding formats on the fly to suite the UPnP client, but for streaming to a PS3 the only format that would need re-encoding is MKV. So I finally gave up on Fuppes looking for something better. PS3 Media Server was no better, in fact I liked it even less than Fuppes, I never could get it to work correctly. So I installed the Mediatomb package from FreeBSd ports to give that a try. Mediatomb is very configurable and can serve just about any file format to UPnP devices including VLC player, Xbox, PS3, and devices using iOS like iPhone, iPad, and Androids if they have the UPnP app. MKV files will need re-encoding for the PS3, but all other formats you can fake the mimetype and extension in the config file and serve them as mpg files of one flavor or the other. AVI is a bad container for streaming since the pointer index is at the end of the file rather than the beginning, and players tend to throw seek errors periodically. But even AVI works well streaming to the PS3 if I set the mimetype to 'video/divx' for files with an .avi extension. I can now stream mpg, avi, Divx, Xvid, and DVD vob files to the Playstation 3 downstairs. The PS3 can also access and play tracks from the iTunes library on FreeNAS as well as individual mp3's. So they can now watch movies and play music from the PS3 in the den without having to boot up the HTPC. I still have to set up mimetypes and mapping for HD video (.ts and .m2ts streams) and it will be finished. Mediatomb uses SQlite and can monitor designated folders on the server. When you drop additional files into the video folders it will automatically add them to the database so they're accessible to a UPnP player. The PS3 is my daughters, I've never owned or used one before. But I have to say the PS3's upscaling feature is amazing when watching DVD's. Streaming a DVD vob file from the NAS the quality is almost as good as Bluray, I'm very very impressed. It provides a really sharp clear picture, the best I've ever seen from a DVD file, and that was over a wireless connection. I'm gonna have to get me one of those PS3 things, she'll probably want hers back.
