Importing iTunes Library from Windows into Songbird on Linux

I'm having real trouble importing my iTunes library/playlists into Songbird. I go to Tools\Options\Media Importer and the iTunes Import/Export tab, locate the iTunes library file, and click import library.

It works for a bit and then says "28114 of 28114 files could not be found". After this, none of those files work in my library (I get a "core media error" when attempting to play them).

I am running this on Linux, and I'm pointing into the other Windows Vista partition to grab the iTunes library file, but the two operating systems can "see" each other just fine and browse files between them.

The error looks like the iTunes library file is pointing to the wrong location, or that pointing doesn't work from within Ubuntu...

Any ideas or suggestions? I can't be the only one who wants to import iTunes info from windows into Songbird on ubuntu...
