trying to burn custom disc

[Fredtatro]

I tried ddpuglass method 2 for a test run to burn a disc from KMA files. I just copied 4 songs to a folder on my internal hard drive. The song list shows the 4 songs and I move them to the play list. I click on the "Add song to write list" then open Write disc. Nothing shows up. When I select the folder the KMA's are in, nothing shows up. Am I missing a step. Can't see any KMAs files to burn to disc.
