Yep thanks for that!

FYI I found that Simple Centre allows you to setup playlists (and you can then play these lists on the /server/), but the 770 Media Streamer application doesn't see those playlists, perhaps they are only available on the server?

I also had a quick look at Twonky - this also features playlists on the server side but I cannot even work out how to set one up yet!

Also I discovered that Simple Centre has a nice facility where you can control the music playback on the server from the 770 MS client. Twonky doesn't seem to have this functionality...

I will now head over to your link and try to add myself to the list of people who would like playlist support of some kind in MS. Its a nice app but to be honest its pretty /useless/ without the ability to save playlists...
