Share iTunes for OS x and iTunes for XP under bootcamp

Question

I want to be able to share one itunes library for both my Mac and Xp (same computer)(Dual boot)
the problem is this.
The iTunes for OS x writes the files as:
file://localhost/Volumes/Data/Sorted%20By%20Artist/
and the XP under bootcamp writes it as this:
file://localhost/Z:/Sorted%20By%20Artist/
the only other file that is a factor is the iTunes Library that can easily renamed to iTunes Library.itl
How can I share ONE iTunes library on both the Mac side and the XP(bootcamp side)
if I cant how can I get XP to indentify the /Volumes/Data/ path to see my files... ("Data" is the name of my Hard drive)

Answer 1

Although this topic was covered under http://discussions.apple.com/thread.jspa?threadID=1750484
it does not explain how to fix the path file errors.
the xml file looks like this..
OS x:
<key>Location</key><string>file://localhost/Volumes/Data/Sorted%20By%20Artist/!!!/!!!%20-%20Me%20And%20Giul iani%20Down%20By%20The%20School%20Yard%20(A%20True%20Story).mp3</string>
XP:
<key>Location</key><string>file://localhost/Z:/Sorted%20By%20Artist/!!!/!!!%20-%20Me%20And%20Giuliani%20Dow n%20By%20The%20School%20Yard%20(a%20True%20Story).mp3</string>
OS x cant see a Z: drive nor can Xp see /Volumes....
