I do know that saving of playlists is not a current feature of MediaStreamer. However many UPnP Media Servers do allow playlists from WMP, iTunes etc to be served by the media server in a similar way to the actual stored media content. I suggest you read the FAQ's of Tversity and Twonky for example to understand better how playlist are created and then re-fed to the media player via the UPnP Server presented media tree. (Although I am aware, Playlists are a feature that I have NOT used so much, so cannot guide you further)

Here is a semi-formal request I made in the Media Streamer Open discussion forum for DIRECT Playlist support, where it would be useful if more users added their vote perhaps https://garage.maemo.org/forum/forum...6&forum_id=251
