I have been a long time user of Tversity as the media server of choice for my PS3. However, a recent newcomer to the game, PS3 Media Server, is proving to be a formidable contender and IMO has surpassed Tversity as the best meda server available for the PS3.
Here are some of its features:
- availabe for Mac OSX, Windows, and Linux
- Ready to launch and play. No codec packs to install. No folder configuration and pre-parsing or this kind of annoying thing. All your folders are directly browsed by the PS3, there's an automatic refresh also.
- Real-time video transcoding via MEncoder, tsMuxer or Avisynth
- DVD ISOs images / VIDEO_TS Folder transcoder
- OGG/FLAC/MPC/APE audio transcoding
- Thumbnail generation for Videos
- You can choose with a virtual folder system your audio/subtitle language on the PS3!
- All formats PS3 natively supports: MP3/WMA, JPG/PNG/GIF/TIFF, and all kind of videos (AVI, MP4, TS, M2TS, MPEG) the ps3 is willing to play
- ZIP/RAR files as browsable folders for pictures/audio files
- Preliminary support for pictures based feeds, such as Flickr and Picasaweb
- Preliminary Internet TV / Web Radio support with VLC, MEncoder or MPlayer
- Lossless 5.1 PCM transcoding with DTS movies (windows only)
The things I really like about this program are it's small memory footprint, its automatic folder refresh, ease of installation but with many user customizable features, and it's excellent handling of mkv's (remux vs transcode).
