I am using the Media Server built into the WRTSL54GS to stream music to my Roku Soundbrdge M1000. Finally have it working with Thibor17rc3. I know Thibor included some updates to get the uPnP media server working. Does anyone know what music type this media server will serve up (mp3 - yes, wma -seems to not work, ogg? aac? alac?)? Also does anyone know what playlist format the media server will be able to use (m3u, wpl, etc.)?
