I have created a cd rom that runs onto a pc. Ihave included the xtras in a 
folder and created a stub file to runthe projector. When i put the cd into the 
drive the cd contains the xtras and plays the application fine. But when i 
install the cd the xtras and one of the quicktime movies doe not copy onto the 
hard drive therefore when i play the application it says one of the xtras is 
missing and the movie (quitime) is also missing yet when played on the disc 
they work fine. Can someone please help?
