Iphoto Not Recognising Itunes Library.


I'm having trouble getting iPhoto to recognise my iTunes library to access music for slideshows. When you go to select the music for a slideshow 'Sample Music' is available, but I don't seem to have access to my iTunes library.

iTunes 4.8
iPhoto 5.0
OSX 10.4

I've run through the suggestion in iPhoto help thus:

"Recreate your iTunes Music Library.xml file. Quit iPhoto, iMovie, iDVD, and iTunes. Click the Finder icon in the Dock, and choose Go > Go to Folder. Type "~/Music/iTunes" or "~/Documents/iTunes" and click Go. Drag the "iTunes Music Library.xml" file to your desktop. Open iTunes and create a new playlist by choosing File > New Playlist. Quit iTunes and open iPhoto to make sure you can see your iTunes library when creating a slideshow."

But to no avail. Any ideas?
