Twonky is a very capable UPnP server. Good choice. I've actually been working with GMediaStreamer in Ubuntu a little more and found the solution to getting all my mp3s to show up in Media Streamer for the 770. I use the following command line option: $ gmediaserver --disable-id3 -ieth1 -v4 ./<path> Before I just used: $ gmediaserver -ieth1 -v4 ./<path> Just thought I'd throw that out there for anyone who might have trouble using GMediaStreamer in the future.
