Burn folders can contain items where the original data resides on an NTFS-formatted volume. When you try to burn a CD and/or DVD with data from an NTFS volume, the burn process may not be completed and the CD or DVD may be left untouched.
NTFS is a read-only disk format for Mac OS X 10.4 Tiger. As a workaround you can copy the data from the NTFS volume to an HFS+ volume, then use the copied data as the source files for the burn folder. You will then be able to burn to a CD or DVD.
