When data is burned to a CD, the ARCHIVE Bit gets changed to READ-ONLY.
Open MY COMPUTER, navigate to the FOLDER where your KMAs are stored, "SELECT ALL" KMAs, Right Click on the selected KMAs, and Click PROPERTIES in the Drop Down Box.
When the PROPERTIES Window comes up, see if the READ-ONLY Box is CHECKED. If it is, Clcik the READ-ONLY check box to UNCHECK it and Click OK.
Now, see if Hoster Plays the KMAs.
It is OK to use CDs to permanently store/backup your KMAs.
But, in this case, you would save yourself a lot of grief by investing in an External HD to Transfer your KMAs.
A IOMEGA 160 Gig External HD costs about $115.
