sonicstage and napster

[mailmail42]

I own a nw-ms70d. I tried to find a network walkman forum, but couldn't find one, which is why i'm here.
1)know any good netork forums on the web)?
2)I'm trying to get napster tracts that I bought and downloaded onto my network walkman, but couldn't figure it out from reading the sony knowledge database, or form sony email tech support. Apparently if I burn the napster tract to an audio cd, I can then rip it with openMG or sonic stage. What format do I burn the napster tract to(audio, mp3, or data), and how do I "rip" it with sonic stage(what is "ripping" by the way?)? I have sonicstage 2.0 installed right now, but I am willing to downgrade to an earlier version if it means I can get napster tracts on my network walkman?
thanks,
