It works !!! I just changed maxScannedSubChannels_ to 1 and it worked.
For information, a printed the value of maxScannedSubChannels_, it is
26. It also works if I set it to 2.

I'm currently copying a cd to view the result, but I imagine this will
take some time.

Do you think my writer has a problem ?
