Shared music folders using VMWare Fusion

I'm a new mac user, i have VMWare Fusion on the mac with XP installed. My Creative Zen does not work with Mac as far as i can tell, so im trying to share my music library (which is on a windows server and works fine in Itune son the mac)...i've mapped the drive, i can access it but it is INSANELY slow. The library is large, 50gb+. Works fine on a real windows on the network and works fine with my mac, but via the VMWare i've tried windows media player and media monkey, it seems to process one song in to the library every 45 seconds which would take a lifetime to finish.

Has anyone else tried sharing like this? Just trying to be able to sync my mp3 player.

 

update: disableing windows firewall on the VM, makes it faster, but still pretty darn slow.
