How can I sync an iriver H10 5GB and use playlists with either Winamp or WMP? - iriver sync issue

Hate iriver anymore, so I use Winamp or Windows Media Player. The only problem is that all the music that I need to sync my iriver does not appear in the playlist, but in the browser, and moved my entire collection of songs on my iriver, I like it or not. Please help!
