When setting up my Ubuntu server I wanted it to be able to stream my media via UPnP/DLNA, I looked at a few solutions including MediaTomb and uShare, however I decided to go with MiniDLNA based on the fact that it was lightweight (my server isn’t the most powerful) and that I have a Western Digital TV Live which plays pretty much any file format meaning I didn’t need the server to transcode my media, MiniDLNA will quite happily however stream media to my other devices, like MP3′s and AVI’s (XviD/AC3) to my Xbox 360.
Installing MiniDLNA is available in the default repositories if you are running Ubuntu 11.10 and it can be installed by running the command
sudo apt-get install minidlna
