Install Hijack V160 or later,
then point your web browser at your empeg using a url like:

where you raplace the 192.168.1.43 with your empegs IP address/machine name.

then follow the blinking lights - you'll get a clickable HTML table of playlist, if you click the first link on each row it sends a Winamp m3u playlist file to your PC, which winamp should then fire up and start playing the playlist.

clicking on the next link will produce another html table like the first showing all the songs for this playlist.
