Express/5.5 problem

The liteonit 52X cdburner that came bundled with nero express is corrupting the last track on an audio cd I am trying to make a backup of. An older litonit 24X burner that came bundled with nero 5.5.3 made a perfect backup copy of the same source audio disk… is this because the digital rights protection works with the newer burner/software and not with the older version??

The last track and the second half of the second to the last track skip badly on the disk created with the nero express and the newer litonit 52X burner. The skipping always starts at the exact same point on every attempt.
Thanks in advance!
