Why anyone would want to swap iTunes for WMP11 is beyond me, but if you must:
“The plug-in enables WMP 11 to interact with your iPod as though it were any portable player. Once it’s connected, you can sync your MP3 library, complete with tags and playlists. Alas, Dopisp doesn’t support any kind of DRM-protected tracks (wouldn’t that be sweet).”
Get it here.
