Issue with GarageBand loops

Hey, I've DMG'd my iLife08 install disk and created a Choices.xml file to install iLife08 and the GarageBand and iDVD extras. Everything seems to install fine (I can browse to /Library/Audio/AppleLoops/ and see all the loop files), but when I go into GarageBand and look at the loops, they are all greyed out, and if I click on one of them it gives me an option to download them (which doesn't work) or install them from CD. However, if I follow Apple's tech note (http://support.apple.com/kb/HT2443) and quit GarageBand, delete the search index in /Library/Audio/Apple Loops Index/, restart GarageBand and then drag the /Library/Audio/Apple Loops folder into the loops browser, it all appears and works fine... However, I can't very well do that with 3000 laptops. Anyone else experience this and have a solution?
